Jewellery Council of SA update

Lorna Lloyd, CEO of the Jewellery Council of SA (JCSA), shares the latest developments from the council’s office

The Jewellery Council of SA (JCSA) is a voluntary, non-profit organisation representing the collective interests of refiners, jewellery manufacturers, retailers, wholesalers and service providers within the industry.

We are excited about our new marketing campaign focused on highlighting the many benefits of JCSA membership, designed to support your business, save you time and money and offer peace of mind in today’s fast-paced environment.

You may have noticed our bite-sized updates across social media, WhatsApp groups and our advertisement in the SA Jewellery News magazine. These short, impactful messages aim to give you quick information about how your business can benefit from being part of a unified, professional network.

The campaign relates to how the JCSA can assist members when transacting with the public and how they can protect themselves from disputes that may arise.

Imagine this scenario: a customer commissions a custom-made ring, but later changes their mind,

after you have already purchased materials. What is your recourse?

The council offers mediation services to help resolve such disputes amicably and professionally. We also review whether jewellers have used recommended disclaimers on invoices, receipts and in-store signage –practices that can prevent disputes before they begin by clarifying terms and customer obligations upfront.

Occasionally, irate customers resort to badmouthing our members on social media. Such online reputational threats can quickly damage a brand and stepping in early can mitigate any damage. The JCSA follows a formal dispute resolution process which begins with a written complaint from the consumer. This ensures neutrality and fairness. The complaint is then shared with the jeweller, who has the opportunity to respond in writing. We aim to resolve these issues swiftly, helping to protect your reputation and business.

Members have access to cost-effective dispute resolution through our mediation and arbitration network, offering an alternative to legal action that saves time, stress and legal fees.

The following are further membership benefits which will be featured in our marketing campaign: • Guidance on legislation impacting the jewellery industry.

• Advocacy on behalf of members, ensuring your voice is heard when approaching government.

• Assistance with government incentives and support programmes.

• Free business listings in the SA Jewellery News Bi-annual Directory and on our website, providing valuable exposure at no extra cost.

• Preferential member rates for exhibitors at Jewellex Africa 2025, the continent’s premier jewellery trade show.

• By being a part of the JCSA, you are not just joining a network – you are gaining a partner dedicated to the success, protection and promotion of your business.

On the topic of Valuation Certificates and Certificates of Authenticity, the JCSA was recently approached to discuss these documents, which play a critical role in consumer confidence, legal protection and industry credibility. South Africa does not currently have legislated national standards regulating who may issue a valuation certificate for jewellery; however, industry-recognised best practices and professional standards are promoted by industry bodies such as the JCSA, which has issued Recommended Standards for Valuations. A copy of the document is available to members on request.

To issue a credible and legally sound valuation certificate, a jeweller or valuer should hold a recognised qualification in gemmology and/ or jewellery valuation, have training in valuation methodology (including knowledge of metals, stones, market values and grading standards) and be prepared to testify in court in the event of disputes, as a valuation certificate is a legal document. Anyone can call themselves a valuer, but without training or credibility, their certificate may be

challenged in court or by insurers. Many jewellers outsource the business of valuations.

A Certificate of Authenticity (CoA) is less regulated and is usually issued by a manufacturer or jeweller to affirm the authenticity of the materials used (eg 18ct gold, natural diamonds), the origin or craftsmanship of the piece (eg handmade, designer pieces) and that the item matches the description provided.

Best practices relating to a CoA require jewellers to clearly state what is being certified (materials, origin, workmanship, etc), include specifications (metal type and purity, gemstone type, weight, clarity, colour and cut), include the jeweller’s contact information and signature, and attach an invoice or serial number for traceability

For precious metals, a CoA is often paired with hallmarking, which verifies metal content. SA follows the Precious Metals Act and hallmarking is optional, but encouraged.

To issue trustworthy and respected valuation certificates or CoAs, jewellers are advised to invest in training, stay updated with market trends and legal obligations, use clear, consistent documentation and be ready to support your valuations with expertise and evidence.

The strength of our association is directly linked to the active engagement of our members. We invite you to participate fully in the opportunities provided by the JCSA to ensure the growth and success of the industry.

We thank you for your continued support and look forward to working together to achieve our shared goals in 2025 and beyond.

ON THE COVER

editor's note

This month’s issue is an exciting one, as we report back on the watch industry’s biggest global event, Watches and Wonders 2025. This year’s edition broke records and truly lived up to its name, setting new standards in both creativity and craftsmanship. We have covered some of the standout moments and trends that emerged from the fair, giving you a glimpse into the future of fi ne timepieces.

Continuing the theme of horology, we also take a closer look at the evolution of watches, from traditional mechanical marvels to cuttingedge, smart wearables. Recently, we ran a poll on our Facebook page, asking our readers whether they still wear classic watches – and the results were fascinating. While many have embraced the practicality and features of smartwatches, there is still a strong love for classic timepieces. Personally, I wear both – my smartwatch is a daily companion for its fi tness tracking and functionality, but when it comes to formal occasions, nothing beats the timeless elegance of a classic wristwatch.

We are also thrilled to announce that Jewellex will have a fresh, new look this year! The show will be hosted at an exciting new venue, The Galleria in Kramerville, Sandton, and will take place from 28-29 September. The SAJN team cannot wait to see all of you there and connect with the heart of the local jewellery industry.

Finally, I want to express my sincere gratitude to our loyal readers and advertisers. Your ongoing support and positive feedback mean the world to us. We are proud to serve this dynamic industry and we take that responsibility very seriously. As always, we would love to hear from you, so please let us know what you would like to see more of in the magazine.

Happy May and happy reading!

Jewellex Africa announces new venue and dates for 2025

The Jewellery Council of SA (JCSA) has announced that Jewellex Africa, the country’s premier jewellery and watch trade exhibition, will be relocating to a new venue in 2025. The event will take place from 28-29 September at The Galleria, Kramerville, Sandton, Johannesburg.

This strategic move follows a thorough review by the Jewellex Committee, who identified the need for a venue that would not only accommodate the show’s continued growth, but also offer a modern, sophisticated setting in line with the evolving vision of the event.

The Galleria has been selected as the new home of Jewellex Africa due to its contemporary design,

versatility and proven track record of hosting high-calibre events. The venue provides enhanced exhibition space and a more streamlined layout, most notably the advantage of housing all exhibitors on a single level. This will contribute significantly to an improved visitor experience and greater exhibitor visibility. In addition to the venue change, the event dates have been adjusted. Previously held earlier in the year, Jewellex Africa 2025 will now take place later, a change made possible by the availability offered by the new venue.

This relocation represents a significant milestone in the evolution of Jewellex Africa and reflects the JCSA’s commitment to

ensuring the continued relevance, impact and prestige of the show within the regional industry.

“We’re confident that The Galleria will provide the ideal environment in which to showcase the best of the South African and international jewellery trade,” says Lorna Lloyd, CEO of the JCSA. “We look forward to welcoming industry stakeholders to a revitalised Jewellex Africa in this exciting new space.”

Joint statement on addressing colour instability in sapphires and rubies

The World Jewellery Confederation (CIBJO), the American Gem Trade Association (AGTA) and the International Colored Gemstone Association (ICA) have once again raised concerns about the presence of irradiated rubies and sapphires in the market, particularly those sourced from Sri Lanka.

These gemstones, which exhibit a temporary, but appealing colour, were initially addressed in a 2022 press release titled Irradiation of Rubies: A Cautionary Note. The issue was further highlighted in the 2024 pre-CIBJO Congress Special Report, produced by the CIBJO Coloured Stone Commission, which focused on the colour stability of yellow, orange and padparadscha sapphires. As the widespread use of irradiation treatment in coloured gemstones continues, the report emphasised growing concerns about the stability of the resulting colours, some of which are unstable over time.

Recently, the AGTA issued an “Important Notice” drawing attention to the matter in the USA, where it has been reported that many dealers have stopped purchasing yellow, peach and padparadscha sapphires, as well as rubies from Sri Lankan merchants, due to fears regarding colour instability. Many of these gemstones are reportedly prone to colour fading, shifting to almost white or light pink hues, or – in the

case of irradiated rubies – turning dark red as time passes. The AGTA also indicated that some vendors may be using undisclosed radiation sources to create the temporary colour effects.

In response to the AGTA’s notice, the Sri Lankan Gem and Jewellery Association (SLGJA) acknowledged the issue and confirmed the launch of an industry awareness campaign. The association also expressed its commitment to improving test reporting standards and promoting full disclosure of treatments. To support these efforts, it announced plans to engage in policy and regulatory discussions aimed at introducing stricter regulations and penalties for the use of undisclosed treatments.

CIBJO, the AGTA and the ICA, representing their global memberships, urge authorities in Sri Lanka and other countries to address the concerns surrounding irradiated rubies and sapphires, in line with the SLGJA’s proposed actions. This matter requires immediate attention, as the continuation of the current situation will likely have a detrimental effect on the industry and erode consumer confidence in coloured gemstones.

The three organisations welcome the SLGJA’s proactive response and look forward to the implementation of best practices that will strengthen the global gemstone trade.

2025 JCSA roadshow dates announced

The Jewellery Council of SA (JCSA) has announced the dates for its highly anticipated 2025 Roadshows, a flagship event series aimed at uniting and engaging professionals from across the country's jewellery and diamond sectors.

The Durban roadshow will take place on Wednesday, 2 July, followed by Cape Town on Thursday, 3 July and Johannesburg on Thursday, 10 July. All events will commence at 18:00.

Open to JCSA members, non-members and members of the Diamond Association, the roadshows offer a valuable platform for industry stakeholders to connect, network and stay informed about the latest developments and initiatives within the sector.

“These events are more than just meetings –they’re opportunities for collaboration, knowledgesharing and strengthening the future of SA’s jewellery industry,” says Lorna Lloyd, JCSA CEO.

Further details, including venues, will be shared in the coming weeks.

Gemﬁelds secures loans to support operations as losses deepen

Gemfi elds reported a signifi cant 2024 fi nancial loss, driven by sluggish gemstone demand, turning to borrowing to sustain operations.

The company expects a US$100,8 million loss for the year, up sharply from 2023’s US$2,8 million, due to an impairment on its closed Kagem emerald mine in Zambia and a slowdown in emerald demand caused by oversupply and competition. Lower production of premium rubies from Montepuez in Mozambique also hurt results. Revenue fell 19% to US$212,9 million.

“Market conditions throughout 2024 proved more challenging than we had initially

anticipated,” says CEO Sean Gilbertson. “Revenues from both emerald and ruby auctions were substantially lower.”

With Kagem operations still suspended, only stockpiled emeralds are being processed.

To stabilise fi nances, Gemfi elds is seeking shareholder approval to issue over 556 million shares to raise US$30 million. It also secured a US$13,4 million loan after failing to fi nalise any asset sales, including its Fabergé business.

“We explored options for Fabergé to address a near-term shortfall,” Gilbertson adds. “But the process didn't yield the certainty of funds within the desired time-frame.”

Sotheby’s unveils over US$100 million in rare diamonds in Abu Dhabi

Sotheby’s has launched an extraordinary exhibition in Abu Dhabi showcasing over US$100 million in rare diamonds, led by the Mediterranean Blue, a 10,03ct diamond valued at US$20 million and headlining May’s Geneva High Jewellery sale.

Marking Sotheby’s fi rst Abu Dhabi event since 2009, the exhibition is open to the public until 10 April at

the Bassam Freiha Art Foundation on Saadiyat Island. It off ers a fi rst-ever public viewing of the Mediterranean Blue, while other showcased diamonds are available for private sale.

Katia Nounou Boueiz, Sotheby’s Deputy Chairperson for the Middle East, says: “Bringing together treasures never seen

PlatAfrica’s 2024 collection available online

before and sharing them with the public is one of the most fulfi lling aspects of our work. This exhibition, the fi rst of its kind in the region, marks a monumental return to Abu Dhabi.”

The event highlights not only the diamonds’ beauty, but also Sotheby’s commitment to the Middle East and its global collector base.

Annually, Anglo American Platinum, Platinum Guild International (PGI) India and Metal Concentrators host the PlatAfrica jewellery design and manufacture competition. The event celebrates and supports South Africa’s platinum industry by giving student, apprentice and professional jewellers the chance to work, experiment and innovate with the metal. PlatAfrica showcases platinum’s strength and beauty, while revealing SA’s glowing jewellery talent.

Each year an original theme inspires one-of-a-kind, statement jewellery pieces.

The PlatAfrica store, exclusively online, off ers the public a chance to invest in platinum and in South African jewellery. View or shop the 2024 collection at: https://plat.africa/.

New cohort joins De Beers Enterprise Development Project

The De Beers Group, in partnership with Raizcorp, has welcomed four emerging businesses into its Enterprise Development Project for Diamond Beneficiators. The programme aims to drive inclusive growth in South Africa’s diamond sector by equipping entrepreneurs with the tools to scale and thrive

The De Beers Group, in partnership with business incubation specialist Raizcorp, has officially launched the third intake of its Enterprise Development Project for Diamond Beneficiators, welcoming four emerging enterprises into the programme. This milestone reinforces De Beers’ continued commitment to driving growth, transformation and inclusivity in SA’s diamond beneficiation sector.

First launched in 2016, the three-year programme supports entrepreneurs across the entire diamond value chain, from rough diamond purchasing, cutting and polishing to jewellery manufacturing, marketing and

distribution. It provides a comprehensive suite of support services, including tailored technical, operational and strategic guidance designed to help businesses scale sustainably and contribute meaningfully to both the local and global diamond economies.

The four businesses which make up the 2025 cohort include Axel & Co, Shine Jewellery & Accessories, Elegânté and House of Lemba Design. These companies, which specialise in jewellery design, manufacturing and repair, were selected from a pool of emerging enterprises identified by stakeholders from across the industry. Each company met the programme’s regulatory and operational criteria, ensuring they are well-positioned to add value within the beneficiation pipeline.

Speaking at the launch of the programme at Raizcorp on 17 April 2025, James Kirby, Senior Vice-President of Product Planning and Delivery at De Beers, said: “As we launch the third intake of this transformative programme, I’m reminded that real, lasting and inclusive progress is never accidental. It’s the product of consistent vision, intentional action and the collective will to create

something greater than ourselves. It requires courage, collaboration and, above all, clarity of purpose. That clarity lives at the heart of our Building Forever Sustainability Strategy – our ongoing commitment to ensuring that the story of diamonds isn’t only about what’s unearthed, but about the longterm positive impact we create well beyond the life of our operations.”

Allon Raiz, CEO of Raizcorp, said: “Every big business starts small, but not every small business becomes big. Ninety-six percent of businesses don’t scale because they don’t know how. The De Beers programme will ensure that every entrepreneur who participates will be given the know-how and guidance they need to scale their business.”

The selected businesses share a passion for transforming precious metals and gemstones into jewellery of exceptional brilliance

and beauty. “For me and my team, the journey we’re embarking on with De Beers and Raizcorp will mean realising our dreams of growing into a self-sustaining business that contributes positively to SA’s economy by creating employment and imparting knowledge and skills to fellow South Africans in the jewellery industry,” added Noxolo Mseleku, founder and MD of Elegânté.

To date, 10 diamond beneficiation companies have benefitted from this ground-breaking project since its inception. Of these, 60% are women-owned and 80% are blackowned. Notably, the programme played a key role in the appointment of De Beer’ first majority black-owned sightholder in January 2023, Molefi Letsiki Diamonds, an alumnus of the Enterprise Development project.

The programme continues to represent a powerful example of how effective collaboration between industry, government and entrepreneurs can unlock the full potential of local beneficiation and contribute to building a more inclusive, resilient diamond economy.

SA jeweller takes home world’s top art jewellery award

South African jeweller Geraldine Fenn has won the prestigious 2025 AJF Solo Exhibition Award, securing the largest cash prize in international art jewellery. She will receive US$20 000 to fund a groundbreaking solo exhibition in Montreal, Canada, exploring themes of colonial history and contemporary adornment

In a landmark achievement for South African contemporary jewellery, artist and gallerist Geraldine Fenn has been announced as the winner of the inaugural Art Jewelry Forum (AJF) Solo Exhibition Award, the largest art jewellery cash award currently offered in the USA. The award, valued at US$20 000, will fund the development and production of a solo exhibition, to be hosted at Galerie Noel Guyomarc’h in Montreal in 2025.

Launched this year by the AJF and founded by Arizona-based collector Linda Peshkin, the award was established to support ambitious, stand-alone exhibitions by art jewellers from around the globe, especially those who might not otherwise have the resources to realise their vision. Open to artists of any age or nationality, the 2025 edition drew a strong field of applicants, reflecting the vibrancy and diversity of global contemporary jewellery today.

A compelling and courageous proposal Fenn’s winning proposal impressed the jury with its conceptual strength, technical ambition and deeply

personal perspective. The forthcoming exhibition will reflect her ongoing exploration of colonial histories and the politics of adornment. Through her signature narrative pieces, crafted from silver, trade beads, vintage materials and found images, she re-imagines and reframes European portrait jewellery, interrogating its role in shaping perceptions of power, identity and ownership in the context of Africa’s colonial past.

Her upcoming body of work will also mark a new chapter in her practice, as she begins to explore the age-old Italian technique of micromosaic, a meticulous process involving the setting of tiny tesserae (small blocks of stone, tile, glass or other materials) to form intricate images. In tandem with this, she will expand her collaboration with Marigold, a Zimbabwean beading collective. Together, they will produce large-scale, woven panels that translate digitally pixelated interpretations of colonial portraiture into beadwork, creating a meaningful intersection between digital imagery, historical narratives and traditional craft practices.

“This award is an extraordinary opportunity,” says Fenn. “It enables me not only to make new work, but also to travel, learn new skills and collaborate across borders. Being recognised internationally for a project so rooted in African history and identity is incredibly meaningful. I’m truly honoured to be the first recipient of this award.”

A South African voice on a global stage

Fenn, who co-founded the Tinsel Gallery in Johannesburg in 2006, has long been a key figure in the South African jewellery art scene. With degrees in archaeology, classics, art history and fine art, her work reflects a deep intellectual and cultural engagement. Her pieces, often witty, symbolic and politically astute, have been widely exhibited in countries including Sweden, Brazil, France and Portugal. She has also been selected twice for Schmuck, the prestigious juried exhibition which is a central feature of Munich Jewellery Week, the world’s leading event for contemporary jewellery.

Yet despite this success, Fenn says that working from Johannesburg can sometimes feel isolating. “In my studio, I often feel very far away from the rest of the art jewellery world. This award changes that. It offers me a real connection to an international community and a chance to share my work with new audiences.”

Praise from an esteemed international jury

The award was adjudicated by a distinguished panel of international experts: Caroline Broadhead, artist and educator (UK), Mike Holmes, gallerist and curator (USA) and Grace Lai, curator and art historian (New

“Fenn, who cofounded the Tinsel Gallery in Johannesburg in 2006, has long been a key figure in the South African jewellery art scene.”

Zealand). Each spoke about the high calibre of applications received and the difficulty of narrowing the selection to just one winner.

“Serving as a jury member for this award has been both an honour and a challenge,” said Lai. “The technical mastery, conceptual depth and creative vision on display reaffirm the strength and dynamism of contemporary jewellery. Geraldine’s proposal demonstrated not only exceptional talent, but also the potential to contribute meaningfully to the discourse around identity, history and ornamentation.”

Holmes agreed. “The ideas and conceptions shown in the submissions were thoughtful and inspiring. Geraldine’s project stood out for its powerful synthesis of concept, craft and collaboration,” he said.

“We all felt a great reluctance to select only one of the excellent and deserving applicants. It was a privilege to engage with such high-level work and Geraldine’s proposal truly captured our imagination,” added Broadhead.

A breakthrough for African contemporary jewellery For South Africa and the wider

Southern African region, Fenn’s win represents more than just a personal accolade: it signals a broader shift in the international jewellery world, where voices from the Global South are increasingly being recognised for their innovation, relevance and critical perspectives. As global conversations about decolonisation, representation and cultural exchange gain momentum, artists like Fenn are bringing new narratives, techniques and collaborations into the spotlight.

Founded in 1997, the AJF is a non-profit organisation dedicated to the advocacy, education and promotion of art jewellery globally. With a vibrant community of artists, collectors, educators, writers and galleries, the forum commissions critical writing, supports exhibitions and provides financial support to contemporary jewellers through grants and awards. Its website, artjewelryforum.org, is one of the most respected online resources in the field.

With the inaugural Solo Exhibition Award now setting a new benchmark for support and visibility in the sector, Fenn’s upcoming exhibition is poised to be a standout moment on the international jewellery calendar in 2025.

Watches and Wonders:

a record-breaking celebration of time

In a dazzling celebration of horological craftsmanship and innovation, Watches and Wonders Geneva 2025 concluded on a historic note, breaking attendance records and further solidifying its status as the world’s premier luxury watch fair. With over 55 000 visitors, an increase of 12% over the previous year, the salon drew an unprecedented crowd who included industry professionals, enthusiasts, collectors, celebrities and the next generation of watch-lovers.

Held under the stewardship of the Watches and Wonders Geneva Foundation (WWGF), the event attracted 6 000 retailer representatives (+5%) and 1 600 journalists (+7%). The public days were equally successful, selling over 23 000 tickets, marking a 21% increase year-on-year. The excitement and anticipation surrounding the event spilt into the digital realm, with the official hashtag #watchesandwonders2025 reaching an estimated 700 million people, up 17% from 2024, thanks to widespread engagement from influencers, journalists, YouTubers and exhibiting brands.

The Watches and Wonders Geneva 2025 fair, held from 1-7 April, set a new benchmark in the watchmaking industry, attracting over 55 000 visitors – a 12% increase from the previous year. This year’s event featured 60 brands, including prestigious maisons and innovative independents, underscoring Geneva’s status as the global hub of horology

“Watches and Wonders has established itself not only as a mustattend inter-professional event, but as a platform for expression for the watchmaking maisons. The event gives each of them the opportunity to visually express their own universe, to see and wear beautiful creations and to share a common passion. Media, medium and mediator,” said Cyrille Vigneron, President of the WWGF.

Every aspect of this year’s show reflected the vitality of the Swiss watchmaking industry. More than 43 000 hotel nights were booked (+17%), while 12 000 retail meetings were held (+21%), indicating that the event continues to be a major commercial driver and networking hub for the global timepiece sector.

A creative momentum was palpable throughout the halls, with a wealth of new releases launched to great acclaim. Some brands celebrated their storied heritage, while others took bold steps forward with updates to iconic collections. Women’s timepieces stood out, particularly in the high jewellery segment, with an emphasis on reduced case sizes, textured dials and bold colour choices, all offering new avenues for design differentiation. A notable trend was the proliferation of skeleton watches, a reflection of the enduring fascination with mechanical precision and transparency. Several launches marked world premières and new records, underscoring the relentless drive for technical excellence.

The salon welcomed 60 exhibiting brands, ranging from the industry’s largest houses to independent innovators. Names such as Rolex, Patek Philippe, Cartier, TAG Heuer, Vacheron Constantin, Hublot, IWC, Chanel and Grand Seiko shared the stage with smaller ateliers, including Armin Strom, Laurent Ferrier and Christiaan van der Klaauw, illustrating both the breadth and depth of contemporary watchmaking.

INTERNATIONAL FAIR

Adding to the event’s star power, celebrities such as Simone Ashley, Usain Bolt, Roger Federer, Carl Lewis and Hans Zimmer were spotted engaging with the latest creations, further elevating the global profile of the salon and reinforcing its cross-over appeal spanning luxury, sport and entertainment.

Equally impressive was the success of the “In the City” programme, which brought the spirit of the salon into the heart of Geneva. Sold-out workshops, guided tours and lively boutique animations transformed the city into a watchmaking wonderland. The Thursday night’s festivities culminated in a Bon Entendeur concert, with crowds of all ages celebrating a vibrant springtime of horology.

“Every aspect of this year’s show reflected the vitality of the Swiss watchmaking industry. More than 43 000 hotel nights were booked (+17%), while 12 000 retail meetings were held (+21%), indicating that the event continues to be a major commercial driver and networking hub for the global timepiece sector.”

NOTEWORTHY NEW RELEASES

Rolex Introduced the Oyster Perpetual LandDweller, a vintage-inspired model featuring a unique honeycomb dial design. Prices start at US$14 900, with the platinum version reaching US$63 500.

Vacheron Constantin Unveiled the Les Cabinotiers Solaria Ultra Grand Complication, the most complex wristwatch ever made, comprising 1 521 components.

Cartier Revived the Tank à Guichet after two decades, offering a fresh take on this classic design.

Bulgari Introduced the Serpenti Aeterna, a timepiece which combines white gold and diamonds, exemplifying the brand’s mastery in blending jewellery and watchmaking.

Piaget Launched a white-gold Polo 79 watch, adding a luxurious option to its iconic collection.

The next generation was also very much in focus. Nearly 10 000 young people had the opportunity to explore the art and science of watchmaking through school visits, educational workshops, vocational presentations and events tied to the SwissSkills 2025 initiative. The Watchmaking Village served as a key destination, welcoming students and schools from across the region to engage directly with the craft.

The Watches and Wonders Geneva Foundation, founded in 2022 by Rolex, Richemont and Patek Philippe, welcomed new board members Chanel, Hermès and LVMH in 2024, creating an even more powerful alliance to promote the art of watchmaking globally. With Geneva firmly established as the flagship event, the foundation continues to expand its vision of connecting tradition with innovation and education.

As the curtain falls on this record-breaking edition, Watches and Wonders Geneva 2025 has not only exceeded expectations, but reshaped the standard for what a global luxury trade event can be. A celebration of creativity, precision and passion, it was a week which confirmed, once again, why this event remains the beating heart of the watchmaking world.

The evolution of watches

The watch, once a simple tool for telling time, has evolved into a symbol of personal style, craftsmanship and luxury. Over centuries, it has transformed from a pocket-sized accessory to a statement piece of jewellery, combining both precision engineering and aesthetic appeal

Early beginnings: the birth of the timepiece

The concept of a portable timepiece dates back to ancient civilisations which used sundials and water clocks to measure time. However, it was not until the 16th century that the first mechanical watches were created. In 1505, German inventor Peter Henlein, a clockmaker from Nuremberg, developed one of the earliest portable watches, known as a

“Nuremberg egg”. It was powered by a spring mechanism, which was a revolutionary leap in timekeeping technology.

These early pocket watches were bulky and primarily used by the wealthy. They were often more ornamental than practical, adorned with intricate engravings and precious metals, reflecting the social status of the owner, rather than their function.

The 17th and 18th centuries: refining timekeeping

The 17th and 18th centuries saw significant advancements in watchmaking. The pocket watch became more refined and watchmakers like AbrahamLouis Breguet and Jaquet-Droz introduced innovations such as the balance spring (also called a hairspring), which greatly improved the accuracy of watches.

During this period, watches were still a luxury item, crafted with painstaking detail and often used as a status symbol by the aristocracy. The watches were often decorated with gemstones, engravings and gold, showing their dual purpose as both functional objects and decorative pieces.

One notable example was the watch created by Swiss watchmaker Breguet in the late 18th century. He revolutionised the industry with the development of the tourbillon, a mechanism which counteracted the effects of gravity on the balance wheel, enhancing the accuracy of mechanical watches. Breguet’s watches were not only functional, but works of art, incorporating fine metals and diamonds, thus blending technical prowess with aesthetic value.

The 19th century: the Industrial Revolution and mass production

The Industrial Revolution of the 19th century played a pivotal role in the evolution of watches. With the advent of mass production

techniques and more standardised manufacturing processes, watches became more accessible to the middle class. During this time, pocket watches continued to dominate, but they were now more affordable and suppliers such as the Waltham Watch Company and Elgin emerged in the USA, offering a range of timepieces at different price points.

Watches from this period were often encased in gold, silver or brass, with many still adorned with intricate designs. However, the focus began to shift towards functionality, as well as style. New manufacturing methods made it easier to produce reliable, durable watches at lower costs, which also made the technology more available to a broader audience.

The early 20th century: the rise of wristwatches

Although wristwatches had existed in limited quantities for decades, they truly came into prominence during World War I. Soldiers found that pocket watches were cumbersome to use in the heat of battle, so wristwatches – already in use by some women – became the practical solution, marking the beginning of their dominance in the market.

“From their humble beginnings as pocket watches to their current status as both functional tools and symbols of luxury, the evolution of watches is a testament to human ingenuity and craftsmanship.”

The transition from pocket watches to wristwatches also had a profound effect on the jewellery industry. No longer merely functional items, wristwatches began to be crafted with the same level of precision and artistry as other fine jewellery. They were adorned with precious metals, diamonds and other gemstones, and brands such as Cartier, Rolex and Patek Philippe rose to prominence, offering watches that were not only timepieces, but also items of jewellery.

The

mid-20th century: the golden age of watchmaking

The mid-20th century marked the golden age of mechanical watches. During this time, Swiss brands such as Rolex, Omega and Audemars Piguet cemented their places in the luxury watch market. Innovations such as the automatic movement (which used the wearer’s motion to power the watch) further enhanced the convenience and appeal of mechanical watches.

In the 1940s and 1950s, iconic models like the Rolex Submariner, the Omega Speedmaster and the Patek Philippe Calatrava were introduced, each becoming a symbol of craftsmanship, luxury and style. These watches were engineered to perfection and paired with elegant designs, reinforcing the idea that a watch was both a functional tool and an essential piece of jewellery.

Wristwatches also became status symbols during this period, with celebrities and influential fictional characters such as James Bond (who wore an Omega in films) elevating the status of particular brands.

The 1970s: the quartz revolution

In the 1970s, a groundbreaking shift occurred in the watch industry with the introduction of quartz technology. The quartz watch used a battery-powered movement, which was far more accurate and cost-effective than traditional mechanical movements. The Swiss watch industry, which had dominated the market for centuries, was initially slow to adopt this technology, allowing Japanese companies such as Seiko and Citizen to lead the charge with affordable, high-precision quartz watches.

The success of quartz watches led to the “Quartz crisis” or “Quartz revolution”, where the dominance of traditional Swiss mechanical

watches was challenged. This period saw many traditional watchmakers struggling to compete, while Japanese brands surged in popularity. However, Swiss watchmakers responded with innovations, integrating quartz movements into their luxury timepieces and adopting designs that combined modern technology with the traditional craftsmanship for which they were known.

The 21st century: smartwatches and the future of timepieces

In the 21st century, the watch industry faced yet another transformation with the advent of smartwatches. These digital timepieces, such as the Apple watch and various models from brands like Samsung and Fitbit, represent a fusion of advanced technology and traditional timekeeping. While they are primarily focused on functionality, offering features such as fitness-tracking, health-monitoring and app integration, they also serve as fashion statements.

Watches as jewellery

While the evolution of watches has been defined by technological advances, the relationship between watches and jewellery has been equally crucial. In modern times, many high-end watches have been seen as masterpieces of design and craftsmanship, often adorned with diamonds, gold and other precious stones. For instance, the Patek Philippe Grand Complication or the Audemars Piguet Royal Oak are not just timepieces, but highly collectable luxury jewellery items which signify wealth, status and refinement.

As watches continue to blend technology with artistry, they remain an essential part of the jewellery world. Today, the line between watches and jewellery is more blurred than ever. With mechanical, quartz and smart technologies co-existing, the evolution of watches continues to captivate enthusiasts, collectors and consumers alike.

Luxury watch brands have responded to this new era by incorporating smart technology into their traditional designs. For example, TAG Heuer and Omega have developed hybrid smartwatches that blend mechanical movements with digital functionality, offering a glimpse into the future of horology. These innovations represent the latest step in the evolution of watches, combining the artistry of fine jewellery with cutting-edge technology.

From their humble beginnings as pocket watches to their current status as both functional tools and symbols of luxury, the evolution of watches is a testament to human ingenuity and craftsmanship. Watches have undergone tremendous changes in terms of design, functionality and technology, but they have always remained a focal point of both timekeeping and fashion. As the watch industry continues to innovate, it will undoubtedly continue to push the boundaries of design and technology, ensuring that the timepiece remains a cherished object of both utility and beauty for generations to come.

Tools of the trade

As the jewellery industry continues to evolve, staying ahead of the curve means embracing the latest tools, technologies and machinery that enhance both creativity and efficiency. This month, we are spotlighting innovations which are making waves in the watches and jewellery finishing sector

The OTEC EF-Nova is the latest innovation in automated electro-finishing, designed for intricate jewellery and watch components. This compact plug-and-play machine combines automation, sustainability and precision to produce consistently flawless finishes, even on complex geometries and hard-to-reach areas.

Equipped with eight pre-installed programs and intelligent media container recognition via RFID technology, the EF-Nova simplifies the process while delivering high-gloss results without micro-scratches. Its advanced hybrid system merges electro-finishing with OTEC’s mass-finishing technology, ensuring surface perfection in both fine details and larger parts.

The EF-Nova processes rings, earrings and pendants in gold, silver, copper, brass, stainless steel, tool steel and cobalt chromium. It enables up to 100% gold recovery with no material loss, eliminating traditional polishing or acid baths. As a cyanidefree system, it offers an environmentally responsible alternative. With reproducible process times under 30 minutes and the ability to process six rings at once, it is ideal for jewellers seeking efficiency without compromising quality. An optional special holder allows precise handling of individual workpieces.

Designed for versatility and performance, the OTEC Eco Maxi Tumbler delivers professional-grade finishing across a wide range of materials and applications. This system is ideal for polishing, grinding, deburring and smoothing everything from jewellery pieces to watch components.

The machine is suitable for use on gold, silver, platinum, brass, stainless steel, ceramics and even gemstones. Common applications include rings, pendants, bracelets, bangles, necklaces, choker jewellery, watch cases and bands, as well as mechanical watch parts.

A key component of the Eco Maxi’s success lies in the precision of OTEC’s process

media. Whether working with wet or dry finishing methods, the right combination of machine and media ensures results that rival hand-polished surfaces. Wet-finishing uses a water and compound mixture to rinse away particles and prevent clogging, making it especially effective for bulk goods that require simultaneous deburring and polishing. In contrast, dry-finishing uses abrasive granulates combined with polishing pastes or powders to produce a high-gloss finish through friction. This method is particularly well-suited for polishing ceramics and carbide.

For enhanced grinding during wet processes, OTEC’s Wet Grinding Paste is recommended. Used in conjunction with porcelain polishing media, it increases grinding performance and is also effective for refreshing blunt tools.

With its advanced finishing technology and wide range of applications, the Eco Maxi Tumbler is an indispensable addition to any professional workshop.

Due to their water content, opals can be susceptible to drying out, especially when exposed to dry environments or extreme temperature changes. This can lead to the loss of play-ofcolour, crazing (cracking) or even breakage. Storing opals in water or a humid environment can help maintain their hydration and structural integrity.

Gems Recovered From Sedimentary Rocks

James E. Shigley, Roy Bassoo, and Aaron C. Palke

Sedimentary rocks such as shale, limestone, and sandstone are among the most common rocks exposed on the earth’s surface (figure 1). In actuality they represent only a thin covering of the crust, which mainly consists of igneous and metamorphic rocks. Despite their relatively insignificant volume, many of the major geologic events in the earth’s history are more accurately documented and age-dated by their scientific study. In addition to having economic deposits of oil, natural gas, coal, and certain heavy minerals such as gold and platinum, sedimentary rocks also host important primary and secondary occurrences of many gemstones (Dill, 2018). The occurrences of gems in sedimentary rocks result from two different geological processes. Opal and turquoise, for example, can form in voids or empty spaces by precipitation from water or mineralized solutions, respectively (figure 2). In contrast, other gems such as diamond and sapphire were weathered out of their original igneous or metamorphic host rocks and then carried away by erosion to be later trapped in sediments. Their hardness and resistance to mechanical abrasion allowed these minerals to be transported and then deposited by moving water to create alluvial or placer gem deposits (figures 3 and 4). Both categories of gems in sediments will be discussed in this column.

and the expected mineralogy and phase changes within slab rocks. Overlaying the slab geotherms onto phase diagrams helps to illustrate where water-bearing phases break down and release fl uid, such as the relatively well-accepted loss of most water from warm slabs at relatively shallow depths (<200 km). This is the activity that generates melt and fuels arc volcanoes such as those of the Pacifi c Ring of Fire. Cold slabs, however, can partially bypass this shallow dewatering process and transport a budget of carbonate and water to depths beyond 300 km, where its later release can cause deep-focus earthquakes (figure 3).

The cold slabs can be thought of as having a carbonated crust component and a hydrated/serpentinized mantle peridotite component that lies shielded beneath the crust, toward the interior of the slab. The deep release of carbonatitic melt and hydrous fl uid from each component, respectively, is shown in the two depth profiles in figure 3. The carbonated crust (mid-ocean ridge basalt, or MORB) of the slab surface will intersect a deep depression in its solidus, the curve describing the beginning of melting, meaning it exceeds the melting temperature. Beyond this point, carbonate melting (red arrows) is expected to occur within the top/crustal portion of the slab.

Sedimentary Rock Formation

For hydrated/serpentinized mantle peridotite inside the slab, its stability also depends on temperature. If it remains cool, the serpentine can metamorphose into higher-pressure water-

bearing minerals called dense hydrous magnesium silicates (DHMS) rather than breaking down. DHMS phases are a good vehicle for transporting water, with some carrying as much as 10% or more water by weight. The geotherm for the interior of cold slabs remains in the DHMS stability fi eld far beyond a depth of 300 km (far right in figure 3). The slab in figure 3 is shown defl ecting as it reaches the top of the lower mantle (at 660 km), where there is a change in mantle density and deformability. As the slab stalls and warms up, DHMS phases break down to form minerals that carry much less water, thereby causing water release (blue arrows in figure 3). These are the mechanisms proposed to trigger not only deep-focus earthquakes but also super-deep diamond growth (Shirey et al., 2021).

Inclusions in the smaller, lower-quality varieties of sublithospheric diamonds often show evidence of growth from carbonatitic melts derived from slabs (Walter et al., 2008), but hydrous/aqueous fl uids have also been implicated for some samples (Wirth et al., 2007; Pearson et al., 2014; Palot et al., 2016). Serpentinite in subducting slabs can be relatively enriched in boron, meaning that the eventual breakdown of hydrous minerals from serpentinized peridotite can release boron-bearing hydrous fl uid, which has been linked with the formation of type IIb (boron-bearing) diamonds (Smith et al., 2018). Figure 4 shows a calcium silicate (breyite) inclusion with methane and hydrogen in a type IIb diamond. The original mineral inclusion may have been relatively hydrogen-rich

A three-step sequence of geologic processes results in sedimentary rocks forming on or near the earth’s surface. The first step is termed weathering—the physical, chemical, and biological decomposition of preexisting rocks of all kinds to form finer-sized particles. These particles accumulate and compact in geological basins over time to form new sedimentary rocks. Weathering involves the combined actions of air, water, chemical salts and/or solutions, freezing and thawing temperature cycles, and the effects of plants and animals on rocks. The change in relative abundance of the various minerals from the original rock to the final sedimentary products is a measure of their comparative resistance to weathering.

Where the slab surface temperature intersects the solidus of carbonated mid-ocean ridge basalt (MORB), partial melting may occur (red arrows). At the far right, a cold slab interior remains within the dense hydrous magnesium silicates (DHMS) stability field until the slab stalls and warms up, causing the breakdown of these hydrous phases and the release of hydrous fluid (blue arrows). Large white and smaller brown diamond symbols signify the growth of high-quality gem diamonds (CLIPPIR and type IIb) and low-quality, generally non-gem sublithospheric diamonds, respectively.

For hydrated/serpentinized mantle peridotite inside the slab, its stability also depends on temperature. If it remains cool, the serpentine can metamorphose into higher-pressure water-

by winds (as volcanic ash or fine-grained sand), by the movement of glacial ice, and by gravity (downslope sliding)—these situations, however, are less important for the creation of alluvial gem deposits. After the deposition of sediments, the final step is termed lithification. Sedimentary rocks form when layers or accumulations of clay, silt, sand, and other deposited materials are compacted and cemented by the weight of overlying rocks (figure 6). Before, during, and after lithification, sedimentary rocks undergo physical and chemical changes due to heating, compaction, and reaction with groundwater. Biological agents, including small animals or microbial bacteria, can also be important, as can chemical agents brought in by flowing water or heated hydrothermal solutions. These changes are collectively called diagenesis, and they can be described as grading into a low temperature and pressure form of metamorphism. Textural changes, including compaction and loss of pore space and trapped water, recrystallization,

In a similar way, geologists have recognized a “mineral dissolution series” of the relative stability (or “resistance to weathering”) of common minerals at the earth’s surface (figure 5). This dissolution series is also based on several other factors, including the extent of bonding of silica tetrahedra in the mineral’s crystal structures, as well as the relative resistance of their chemical elements to leaching by water. Minerals that are more resistant to weathering and dissolution are more likely to be retained in sedimentary environments and concentrated in alluvial deposits. The next step is erosion—the process by which solid or dissolved products are transported various distances from the weathering site and are eventually deposited elsewhere as loose, unconsolidated sediments. Erosion acts to lower the overall topography of the land surface. Flowing water is the most important transporting agent for sediments, which can result in the breakage, abrasion, chemical alteration or dissolution, and sorting by size and/or shape of rock fragments and particles. This transport occurs when the velocity of the water overcomes the downward pull of gravity, and the water moves the suspended material. Sediments can also be transported

Sedimentary Rock Classiﬁcation

Continental lithosphere

The nature of a sedimentary rock depends both on the source supply of the sediment as well as the depositional environment in which it formed (including continental, marine, and transitional settings involving water) (figure 7). Most sedimentary rocks can be divided into several groups based on mineral compositions and geologic formation mechanisms. Clastic rocks are composed of rock fragments of varying sizes that are cemented together. When transported by moving agents such as water or wind, sediments often become sorted by particle size before lithification. These rocks include shale, claystone, mudstone, siltstone, sandstone, and conglomerate, with the difference between them being the increasing size of the particles from less than a millimeter to larger than a few centimetres. Most gem minerals discussed here occur in clastic rocks. Biogenic rocks are formed by accumulations of skeletons of large or microscopic organisms or decomposed plant material. These rocks include limestone, dolostone, chert, diatomite, and coal. Chemical sedimentary rocks are formed by inorganic constituents dissolved in and later precipitated from solution when it evaporates at normal surface temperatures. They include some limestone and dolostone (e.g., travertine), phosphorite, evaporates (such as halite), and banded iron-oxide formations.

and the changing of fine-grained rocks into coarser ones, are all forms of diagenesis. During recrystallization, secondary minerals may precipitate in open spaces, and mineral cements such as calcite, silica, and hematite may develop—consequently, rocks become more resistant to erosion. With increasing burial conditions, sedimentary rocks become even more compacted as they are exposed to higher temperatures and pressures, which also results in the solid-state precipitation of low-grade metamorphic minerals such as chlorite. This sequence of changes by which sedimentary rocks form are described here as separate geological processes, but in actuality they merge into one another with no sharp boundaries between them. Sandstone forms from quartz-rich sediments, whereas shale forms from those rich in clays. Limestone forms when calcite and aragonite precipitate out of water containing dissolved calcium, or it forms from the accumulation of corals and shells on the sea floor. Compaction of mixtures

Sedimentary Rock Textures

Oceaniclithosphere

Carbonated slab melting

Hydrous uid

Sedimentary rock formations often display features related to their deposition environment, such as along a river channel or coastline where sediments are deposited. These conditions can result in coarse- or fine-scale layering, banding, or bedding structures. The rocks may also exhibit cross or graded bedding, ripple marks, and mud cracks. Layering, banding, or bedding structures are due to preferential particle orientation and packing, or to the concentration of mineral particles into distinct layers. Folding and faulting of rock layers resulting from local or largescale deformation can occur after sediment deposition and before or after rock consolidation. Sedimentary rocks themselves display various textures resulting from the size, shape, and arrangement (packing and orientation) of the constituent particles. Particle size is of particular importance for geologic field studies because it provides information

The formation of gem minerals in sedimentary rocks (table 1, left column; again, see figure 2) can be summarized as follows: Opal is a hydrated form of amorphous silica produced by the deposition of spherical particles from silica-rich water flowing through cracks, pores, and voids in sedimentary rocks during hotter months as the water itself evaporates. The process is repeated over long periods of time, with the silica particles settling out over time by gravity. These tiny particles arrange themselves into regular layered structures, and they range from about 150 to 400 nanometers in diameter. Opal can produce a “play of colors” appearance by light diffraction. Both gem and non-gem opal occur widely, with the most important sedimentary deposits being in Australia (Rey, 2013; Liesegang and Milke, 2014; Hsu et al., 2015). Fire opal forms by leaching followed

by deposition of silica from water moving through cavities in porous volcanic rocks. Other opal sources include Ethiopia, Hungary, Mexico, and Nevada in the United States. Turquoise is a hydrated copper phosphate that can form in more than one way. One process begins with copper sulfide ore minerals (such as chalcopyrite or bornite) being deposited by higher-temperature hydrothermal solutions to form a mineralized rock. The turquoise forms later when meteoric waters percolate through this rock, and dissolved oxygen in the water reacts with sulfide minerals to produce soluble copper sulfates. The resulting acidic, coppercontaining solution reacts with aluminum and potassium minerals in a host rock to produce turquoise that fills veins, seams, or fractures, sometimes forming nodular masses. It was among the first gem minerals to be mined, beginning more than 2000 years ago in Egypt (Ovissi et al., 2017; Ardekani et al., 2020; Shirdam et al., 2021). Important current sources include Argentina, Armenia, Australia, China, Iran, Mexico, and the United States. Chalcedony forms in volcanic rocks that contain gas cavities, which can then be partially or completely filled with cryptocrystalline

Figure 6. Weathering and erosion of preexisting rocks produces rock particles and fragments which can be carried into bodies of water where they undergo deposition, compaction, and cementation to form new sedimentary rocks.

For hydrated/serpentinized mantle peridotite inside the slab, its stability also depends on temperature. If it remains cool, the serpentine can metamorphose into higher-pressure water-

silica material that precipitates from volcanic fluids from the walls of the cavity inwards. Thus, most chalcedony is not considered a gem that forms in sediments. The one exception is the green chrysoprase variety, which forms as veins, fracture fillings, and nodules in sediments due to the weathering at shallow depths of nickel-bearing serpentinite rocks that are rich in iron and magnesium (Shigley et al., 2009; Sachanbiński et al., 2023). Chalcedony occurrences are found in many localities. Malachite and azurite are copper carbonate hydroxides that precipitate from hydrothermal fluids in fractures or underground spaces as secondary gems, followed by surface weathering and oxidation of a copper ore body. The two mineral aggregations form botryoidal, reniform, fibrous, or stalagmitic masses, with azurite sometimes also occurring as crystals. Malachite can display internal banding patterns. Both minerals have been used since antiquity as mineral pigments for decorative purposes, and both are mined by open pit and from underground workings. The major current source of malachite is the Democratic Republic of Congo, while the less common azurite comes from various localities (Cook, 2001; Kampunzu et al., 2009; El Desouky et al., 2010;

De Putter et al., 2010; Papineau, 2020). Rhodochrosite is a less common manganese carbonate mineral that is found as distinct crystals or massive fracture- or vein-fillings associated with some ore deposits. Larger transparent crystals are sometimes faceted as gems. In a few localities, the mineral forms from dripping water which creates stalactites and stalagmites (Marquez-Zavalia and Craig, 2022). Amber is not a mineral but an organic fossilized resin that was exuded as a sticky substance from the bark of certain trees. Pieces of resin that dropped to the ground became covered by soil. When the trees fell, the resincontaining logs were carried by rivers and tides to coastal regions where they were buried by sediments. Due to the compression pressures and elevated temperatures from the overlying sediments, the pieces of resin were compacted and transformed over geologic time, first to copal and then to amber. While long used as a gem material, amber is important for the science of paleontology since it preserves a wide variety of animal and plant matter (Grimaldi, 2003; Penny, 2010; Ross, 2010). Amber is widely distributed in rocks of Cretaceous age or younger. Historically, the southern coast of the Baltic Sea extending from Poland to

Latvia has been the world’s leading source of this material. Myanmar and the Dominican Republic are other current amber sources (Wolfe et al., 2009; Weitschat and Wichard, 2010; Leelawatanasuk et al., 2013; Sun et al., 2015; Zhang et al., 2020). While being described here as “forming” in sediments, the occurrence of these gem minerals is not directly the result of sedimentation. Instead, it involved physical and chemical changes associated with diagenesis and possibly the action of circulating hydrothermal solutions to introduce the necessary components for gem mineral formation.

Gems Found in, but Not Formed in, Sedimentary

Deposits

For hydrated/serpentinized mantle peridotite inside the slab, its stability also depends on temperature. If it remains cool, the serpentine can metamorphose into higher-pressure water-

The second category of gems occurring in sedimentary environments are those that formed originally in igneous and metamorphic rocks (again, see figures 3 and 4). After these host rocks weathered, their abrasion-resistant gems were transported and are found deposited along current and former stream and river channels, either in loose or more compacted sediments. These gem minerals were formed elsewhere and were transported and concentrated by moving water and other geological processes. A placer deposit is a natural concentration of heavy minerals in secondary sediments caused by the effect of gravity on moving particles. Alluvial or placer mineral deposits have been mined since ancient times. Because they occur at the earth’s surface, they were likely one of the earliest known types of economic ore deposit. They could be worked using simple traditional tools, and the deposits would provide an almost immediate economic reward to the miners. They continue to be significant sources of valuable metals such as gold and platinum (Ibrahim et al., 2020; Nikiforova, 2021; Cabri et al., 2022; Torvela et al., 2022). Placer deposits form as the result of the concentrations of “heavy minerals” in secondary sediments (Patyk-Kara, 2002; Garnett and Bassett, 2005; Stanaway,

Diamond-bearing kimberlite eruption

2012; Nikiforova, 2021). These deposits are masses of unconsolidated or semi-consolidated clastic sediments, formed by surface weathering and erosion of primary rocks and subsequently transported by gravity, water, wind, or ice from their original source. The heavy gem minerals must be hard, durable, resistant to weathering and breakage during water transportation, have a high specific gravity (>2.58), and possess chemical stability to be hosted in placer deposits (Joshi et al., 2021). During water transport, fractured or other poor-quality mineral crystals are often broken up and removed, so the final alluvial deposits often contain better-quality gem material. In some instances, the gem fragments being transported become water-worn or rounded by mechanical abrasion. All of these factors can result in economically valuable mineral concentrations. Such deposits are among the most important sources of a variety of gems including diamond, corundum, spinel, garnet, and quartz, as well as nephrite and jadeite jade (table 1, right column). Such deposits often occur along current or former river channels in unconsolidated or poorly consolidated sediments. In some cases, loose gem diamonds have been carried along by glaciers, which transport but do not sort or separate the placer minerals.

Types of Placer Gem Deposits

Oceaniclithosphere

Placer deposits are classified by Dill (2018) based on the geological factors such as weathering, erosion, and local surface topography that created them (again, see figure 6). Retained Deposits. Eluvial placer deposits are not transported and are located near the point of original gem formation in igneous or metamorphic host rocks. They are found on weathered hillslopes where lighter material has been weathered and/or carried away, but they are often not economically significant enough to support large-scale gem mining.

Rand Refinery enhances community through education

Rand Refinery, one of the world’s leading gold and silver refiners and an operator of one of the continent’s largest low-grade gold recovery smelters, is reaffirming its unwavering commitment to community development by investing in education through a multi-layered approach that extends beyond traditional bursaries.

At a recent meet-and-greet event with students, parents and school representatives, CEO Praveen Baijnath emphasised the company’s belief in the transformative power of education and its ripple effect across families and communities. “Education isn’t just a financial transaction – it’s an investment in people. We don’t just fund potential: we help to unlock it. That means going further than bursaries to address historical debt and other real barriers to academic success,” he said.

Rand Refinery is deepening its commitment to community development by expanding its educational initiatives. Through bursaries, resource donations and support for STEM students, the company is investing in the future of South Africa’s youth

This philosophy is reflected in Rand Refinery’s growing suite of initiatives, in line with government’s mandate, that support access to quality education, especially for students pursuing science, technology, engineering and mathematics (STEM) fields.

In 2023, Rand Refinery launched a merit-based bursary scheme aimed at high-performing students who maintain an average of 70% or above, particularly those enrolled in STEM qualifications. Since its inception, the scheme has awarded 88 bursaries valued at approximately R4,6 million. What sets this programme apart is its holistic design, providing academic funding and ensuring that unresolved financial obligations do not derail students. As part of this commitment, Rand Refinery is settling historical student debt for 11 engineering students at institutions in Gauteng.

The 2025 academic year marks a significant scale-up of the company’s investment in youth. It is awarding nine full and five partial bursaries under its flagship programme to students at universities across the country. Additionally, 10 bursaries are being provided for students in engineering programmes at TVET colleges, along with 10 apprenticeship bursaries for those pursuing trade qualifications at technical colleges. Seven top-performing 2024 matriculants from Ekurhuleni have also been awarded full bursaries to study at universities, as part of Rand Refinery’s socio-economic development drive. This marks a significant leap from the 10 bursaries awarded in 2023 and 26 in 2024.

Rand Refinery’s commitment to education extends to foundational levels as well. In 2025, the company is supporting nine underprivileged schools across six provinces –

Gauteng, KwaZulu-Natal, Mpumalanga, Limpopo, the Free State and the Eastern Cape – by distributing 800 stationery packs which include backpacks, exercise books, pens, pencils, highlighters and other essentials. These were donated to a mix of primary and high schools, including Orange Farm Secondary School (Gauteng), Lwaphundu High School (Limpopo), Tajamane High School (Mpumalanga), Masana Primary School (Mpumalanga) and Refalletsi Primary School (Gauteng).

In addition, Rand Refinery has donated eight STEM resource libraries to selected schools. These libraries – comprising branded cabinets stocked with maths and science textbooks and study

guides for Grade 12 pupils – will support academic excellence in schools such as Ginyiqhinga Secondary (KwaZulu-Natal), Thakameso Secondary (the Free State), Mpilisweni Secondary (Gauteng) and Sitoza Secondary (Eastern Cape).

In alignment with national government priorities, Rand Refinery also partnered with the Ministry of Education in KwaZulu-Natal to donate R100 000 worth of school shoes to underprivileged pupils in January 2025. This initiative reflects the company’s focus on easing the financial burden on families and promoting equitable access to education for all.

“As a corporate citizen, our responsibility extends to the communities in which we operate,” said Baijnath. “Whether we give bursaries, resource libraries or school shoes, our focus is on long-term impact. We’re honoured to play a small part in these youngsters’ educational journeys and contribute to a brighter, more inclusive SA.”

Rand Refinery remains committed to using its platform and resources to empower the next generation of South African leaders through education and sustainable community partnerships. The company’s ongoing initiatives are a testament to its commitment to the educational and socioeconomic development of the country’s future leaders, ensuring that all students have access to the resources they need to succeed.

“In 2023, Rand Refinery launched a merit-based bursary scheme aimed at high-performing students who maintain an average of 70% or above, particularly those enrolled in STEM qualifications.“
