Jewellery Council of SA update

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

Members continue to report that the jewellery market remains highly volatile. Recently, the gold price reached a record high of nearly US$3 000. While the price has slightly declined, gold continues to trade above US$2 900, significantly affecting business.

We believe that the strength of gold this year has largely been driven by increased economic and, to some extent, political uncertainties. These uncertainties are largely tied to the policies of the new USA administration, particularly its approach to tariffs.

A key concern for South Africa is the African Growth and Opportunity Act (AGOA), which allows eligible African countries to export over 1 800 products, including jewellery, duty-free to the United States. President Trump’s stance on South Africa as a beneficiary of this programme is currently in question and we are concerned that AGOA, which is set to expire end September 2025, may be coming to an end.

For several years, the Jewellery Council has co-ordinated trips for South African manufacturers to exhibit at international trade shows in the USA, with sponsorship from the Department of Trade, Industry and Competition. These trips have provided jewellers with an invaluable opportunity to export their products duty-free to the USA.

While I personally believe that AGOA will be extended, considering its significant impact on the USA market, we remain concerned. In anticipation of potential changes, we may need to explore alternative international shows, possibly in Europe, to provide our jewellers with additional export opportunities.

The jewellery industry in South Africa is highly regulated. This includes the Domestic Reverse Charge (DRC) on gold and gold jewellery; the Financial Intelligence Centre Act (FICA); the Precious Metals Act which regulates Jewellers' Permits and Refining/Beneficiation Licences issued by the SADPMR; and the Consumer Protection Act (CPA), which also accredits the Consumer Goods and Services Ombud.

In terms of the VAT Act, the DRC requires the purchaser of gold and gold jewellery to account for the VAT on the transaction, rather than the supplier. This relates to transactions between VAT vendors.

It is important for such VAT vendors to note that regardless of whether they have received any correspondence from SARS regarding revalidation, they are required to comply with the DRC regulations. The onus remains on the vendor to re-validate their registration status. Members are welcome to download the SARS Frequently Asked Questions on the following link: https://www. sars.gov.za/wp-content/uploads/Ops/Guides/ LAPD-VAT-G18-FAQs-on-Domestic-Reverse-ChargeRegulations.pdf.

The Jewellery Council recently reached out to the Financial Intelligence Centre (FIC) to organise an industry-only webinar for our members on the Financial Intelligence Centre Act (FICA), as there is still considerable uncertainty surrounding this complex regulation. The session was well-attended, with 100 members participating. We encourage all members to continue engaging with FIC webinars and explore the available YouTube resources. Here is the link for further reference: https://www.youtube. com/@FinancialIntelligenceCentre.

Additionally, the Consumer Goods and Services Ombud (CGSO) has been accredited under the Consumer Protection Act (CPA) as of 29 April 2015. It serves as the mandatory Ombud scheme for resolving consumer complaints within the consumer goods and services industry, operating through the Industry Code of Conduct and the CPA. As part of this scheme, all companies within the consumer goods and services sector, including those in the jewellery supply chain, are required to register and contribute to the fund.

While the Jewellery Council is not obligated to assist the Ombudsman’s administrators with member registrations, we would like to inform you that they will be contacting you directly to complete your registration with the fund, if you have not done so already.

Their mandatory fees are as follows:

Annual turnover below R1 million = no cost

Annual turnover between R1 million and R50 million = R1 680 per annum

Annual turnover between R50 million and R100 million = R3 500 per annum

Please note that the Jewellery Council will continue to provide a mediatory service between our members and consumers in an attempt to resolve disputes that may arise. Should you wish to register your participation in the meantime with the CGSO, suppliers should submit their Participant Application Form directly to the CGSO by accessing the following link: https://www.cgso.org.za/cgsa/ register/. For further information tel: (011) 781-2607 or visit www.cgso.org.za.

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 Jewellery Council to ensure the growth and success of the industry.

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

editor's note

Welcome to our March 2025 issue! We are thrilled that the response to the announcement that the JCSA has taken the magazine inhouse has been overwhelmingly positive. We are deeply grateful for the support and excitement we have received from the industry and we look forward to continuing to serve as a trusted voice for the trade.

This month, we introduce a new section titled Tools of the Trade. Each month we will focus on a different industry sector and will delve into the tools, equipment and machinery which are vital to it, exploring the latest innovations that are helping to shape the future of craftsmanship and production.

In this issue, we feature an in-depth look at Inferno Gold (formerly Piccolo Fine Designer Jewellery) as it embraces a bold new chapter by incorporating refining into its services. We also highlight the recent MineShift 2025 event where industry leaders, policy-makers, jewellers and visionaries came together to focus on elevating Africa’s presence in the global precious metals market and expanding value-added industries.

Additionally, we take a closer look at how local jewellers can elevate their brand in an increasingly competitive market, explore the latest red carpet trends and share insights from industry events like Mining Indaba 2025 and De Beers’ appointment of Botswana’s Olympic gold medallist Letsile Tebogo as a global ambassador.

We hope you enjoy this issue and look forward to hearing your thoughts as we continue to evolve and grow alongside the industry.

Happy reading!

Namdia suspends CEO and other executives over diamond heist

Namdia Desert Diamonds has suspended its CEO, its Chief Operations Officer and Head of Security following an armed heist which left one employee dead and saw nearly US$20 million in diamonds stolen.

The move comes as the Board of Directors for Namdia, a sales and marketing company owned by the Namibian government, passed a resolution to dismiss the executives temporarily while conducting an internal investigation into the events leading up to the crime, it said.

suspects are in custody, while another died of a selfinflicted gunshot wound. The fourth intruder has not been accounted for. One of the suspects in custody was a Namdia employee at the time of the robbery.

Lelly Usiko, an executive at Namdia who has previously acted as interim CEO, will once again take up the role, filling in for CEO Alisa Amupolo. Meanwhile, Chief Operations Officer Uahoroka Kauta and Security Manager Paulinus Sheyapo will step down. The company has not announced replacements for those two positions.

During the robbery, which took place at the end of last month, four intruders broke in and stole diamonds, killing Namdia’s Senior Protection Officer, Francis “Gosh” Eiseb, as he tried to defend the site. Two of the

“We assure you that the decision to suspend these team members wasn’t taken lightly,” said the board. “However, the investigation and recovery process must now run its course. The Namdia board has decided to take this urgent precautionary step in the business’s best interests, as well as to protect the integrity of both the executives and the investigation.”

The board also took this step to prevent any questions about the independence of the enquiry, it stressed, adding that “the investigation and recovery process must be concluded as quickly as possible”.

The board maintained that at this stage in the investigation, it had no reason to suspect that any employees, other than the one currently in custody, were involved in the robbery. – Rapaport

CPM hosts networking event in Durban

On 13 February, Cape Precious Metals (CPM) hosted an industry networking event in Durban in collaboration with Cape Tools, the Jewellery Council of SA, Teomim Lab Diamonds on Labtradr, Jewellers Network, Spectrometer Technologies and Techsome Technology.

Held at Talloula, 61 Old Main Road, Botha's Hill, from 10:00 to 15:00, the event brought together industry professionals for a day of networking, live demonstrations and a lucky draw.

“Events like these are vital for any industry and I’m grateful that Cape Tools had the opportunity to be part of it, showcasing some of the latest tools and technologies available to the trade,” says Tennille Hoge of Cape Tools.

Inferno Gold has long been a symbol of quality, innovation and bespoke craftsmanship in the jewellery industry. With a rich history of working with precious metals, the company has entered an exciting new chapter: refining. This transition is not just a business evolution, but also a rebrand that marks its commitment to excellence in both jewellery design and refining.

“We decided to rebrand as Inferno Gold and pivot into refining after navigating a decade of challenges in the jewellery industry,” says owner Johann Claassens. “For years, we faced significant hurdles in sourcing refined gold that met our high standards of quality and reliability. This nearly compromised our ability to serve our clients. These experiences drove us to take control of the refining process, creating a refinery that can become a trusted partner for jewellers, artisans and businesses alike.”

Piccolo Fine Designer Jewellery was founded in 2008 by Claassens and his wife Suvette as a premier jewellery design company serving South Africa’s distinguished jewellery market. Over time, the company grew into a respected name in design, with a focus on exceptional craftsmanship. In 2020, Christian Oldewage joined as Director, bringing fresh perspectives to the team.

After a decade of honing its expertise in craftsmanship and the precious metal sector, in 2025 the entity evolved into the state-ofthe-art gold refinery it now is.

“Our mission with Inferno Gold is to provide a dependable, ethical and transparent refining solution, while fostering the growth of the next generation of jewellery-

Inferno Gold: A bold, new chapter

makers and innovators,” explains Claassens. “We’re not just a refinery – we’re a cornerstone of trust, ensuring that others never encounter the same challenges we once faced.”

This transformation allows Inferno Gold to extend its commitment to quality across the entire supply chain, offering premium gold refining services that align with the needs of the jewellery industry.

“With decades of combined expertise in jewellery design and metallurgy, we understand the critical importance of sustainability and trust in the gold refining process,” says Claassens. “Our move into refining allows us to provide a more holistic service to our clients, delivering gold that meets the highest standards of purity and reliability.”

Inferno Gold is committed to ethical sourcing and environmental responsibility. By leveraging cutting-edge technology and refining methods, the company maximises the recovery of precious metals, reduces waste and minimises its ecological footprint.

“We aim to deliver exceptional results for businesses across jewellery, investment and industrial sectors. Whether you’re a jewellery manufacturer, an investor or a small artisan, we offer a streamlined, transparent process designed to meet your specific needs,” says Claassens.

A bold, new identity

The new logo of Inferno Gold embodies the core values of the company: trust, precision and transformation. The central gold circle symbolises continuity, perfection and the infinite value of gold. Its unbroken, flowing design represents the ongoing cycle of refinement and quality that the company strives for every day.

“The elegant swirls within the circle emphasise our commitment to precision and artistry. They evoke movement and transformation, mirroring the meticulous process of refining raw materials into extraordinary creations,” explains Claassens.

Set against a black background, the gold circle stands out with striking contrast, signifying sophistication, luxury and timelessness. Together, these elements represent Inferno Gold’s dedication to excellence, with the circular motif serving as a reminder that the pursuit of perfection is a continuous journey, as endless as the circle itself.

"This transition is not just a business evolution, but also a rebrand that marks its commitment to excellence in both jewellery design and refining."

Celebrating 97 years in the industry

MineShift 2025 took place at Zeitz MOCAA in Cape Town on 2 February, bringing together industry leaders, policy-makers, jewellers and visionaries to focus on elevating Africa’s presence in the global precious metals market and expanding value-added industries

Advancing Africa’s beneficiation journey and redefining luxury

MineShift 2025 marked a pivotal moment in Africa’s drive toward beneficiation and industrialisation. It was created to celebrate the artistry and innovation of African jewellers, artists and manufacturers, offering a platform to showcase the craftsmanship and talent of the industry, while promoting the expansion and advancement of beneficiation on the continent.

“Africa holds immense natural wealth, yet we’ve only scratched the surface of its potential,” said Grant Crosse, Managing Director of leading precious metals refinery and beneficiator MetCon. “It’s time to move beyond exporting raw metals and establish Africa as a global force in value-added production.”

With jewellery comprising 48% of global gold demand, yet Africa producing less than 0,5% of jewellery consumed worldwide, MineShift 2025 called for urgent policy support and investment in local manufacturing.

Beyond discussions, the event showcased Africa’s craftsmanship through exquisite jewellery and fashion, reinforcing the need for the continent’s unique heritage to gain prominence on the world stage. The evening featured a curated display from designers such as Janine Binneman, Vijay Shah, Uwe Koetter and brands like Maxhosa Africa and Sindiso Khumalo.

Held ahead of the Mining Indaba, MineShift 2025 Earth To Art underscored the importance of

formalising artisanal mining to create sustainable economic opportunities. “This isn’t a private vs public issue – it’s about working together to drive meaningful change,” added Crosse.

Set against the backdrop of Table Mountain, the event was an immersive experience featuring thought leaders, signature drinks from Rèmy Martin, The Balvenie, The Botanist and Louis XIII, as well as a collaborative fashion and jewellery showcase. Supported by MetCon, Your Luxury Africa, StoneX, Brinks, Anglo American and the De Beers Group, among others, MineShift 2025 stood as a testament to Africa’s potential to redefine luxury through innovation and craftsmanship.

MineShift is a key networking opportunity aimed at shifting mindsets towards developing a more sustainable future through Africa’s minerals, allowing all Africans to share in the riches of their continent.

A night of brilliance and innovation

On 2 February, MineShift 2025 took place at Zeitz MOCAA in Cape Town, bringing together industry leaders, policymakers, jewellers and visionaries to focus on elevating Africa’s presence in the global precious metals market and expanding valueadded industries. It was an extraordinary event of allure and beauty.

In today’s highly competitive and ever-evolving jewellery market, jewellers face the challenge of standing out, as well as positioning their brands in a way that resonates with their target audience. To achieve long-term success, it is crucial for them to develop strategies that will not only attract the right customers, but also foster lasting relationships with them.

Here is a deeper look at how jewellers can position themselves for sustained growth and success in the modern marketplace:

1. Define your brand identity

A strong jewellery brand goes beyond aesthetics: it tells a story. Define what makes your brand unique:

• Do you focus on ethical sourcing and sustainability?

• Is your design style modern, traditional or avant-garde?

• Do you cater to a specific clientele, such as luxury buyers or everyday wear enthusiasts?

Clarify your brand’s mission and values and ensure that they are reflected in your logo, your packaging and your customers’ experience.

2. Build a strong online presence

With digital shopping becoming the norm, jewellers must leverage online platforms to showcase their work.

Tips for elevating your jewellery brand

The South African jewellery industry is rich in craftsmanship and creativity, but standing out in a saturated market requires more than just exceptional designs

• Website: A professional, mobile-friendly website with high-quality images, a wellwritten “About” section and a seamless shopping experience is essential.

• Social media: Platforms like Instagram and Pinterest are visual goldmines for jewellers. Regularly post behind-thescenes content, customer testimonials and styling tips to engage your audience.

• SEO and e-commerce: Invest in search engine optimisation to improve your online visibility. Consider listing your jewellery on online marketplaces or setting up an e-commerce store.

3. Offer a personalised customer experience

Customers crave meaningful connections with brands. Personalisation can set you apart:

• Offer custom jewellery services to create one-of-a-kind pieces.

• Use customer names in communication and send

personalised recommendations.

4. Leverage influencer marketing and collaborations

Partnering with influencers and industry professionals can expand your reach. Consider:

• Collaborating with local fashion designers for exclusive jewellery collections.

• Partnering with influencers who align with your brand’s aesthetic.

• Working with bridal or lifestyle bloggers to showcase your designs in real-world settings.

5. Prioritise quality and craftsmanship

Nothing builds a brand’s reputation faster than superior quality. Use ethically sourced materials, invest in skilled craftsmanship and ensure that each piece meets high standards. Offering certifications or guarantees can also build trust with buyers.

Moreover, these events allow brands to stay on top of current trends, network with key players in the industry and establish

6. Tell your story through branding and marketing

Customers connect with stories, not just products. Share the inspiration behind your designs, the crafting process or the cultural significance of your pieces through:

• Blog posts or newsletters.

• Video content highlighting your creative process.

• Interactive Q&A sessions on social media.

7. Participate in trade shows and industry events

A local jewellery trade show like Jewellex Africa offers a unique opportunity for jewellery brands to showcase their designs and products directly to a targeted audience of industry professionals, including retailers, buyers and suppliers.

By participating in such an event, a brand can gain valuable exposure and

relationships that could lead to long-term retail partnerships. For a jewellery brand seeking to expand its reach and enter new retail channels, participating in a trade show like Jewellex Africa can be an essential stepping stone to broader market visibility and success.

8. Offer limited editions and exclusive collections

Creating limited-edition pieces or exclusive collections generates

excitement and urgency among buyers. Limited releases can enhance the perceived value of your brand and attract collectors.

Elevating your jewellery brand requires a mix of strategic branding, digital marketing and exceptional craftsmanship. By creating a strong identity, engaging with your audience and consistently delivering quality, you can carve a niche in the market and build a lasting legacy.

Tools of the Trade

KrugerRand Checker

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 that are making waves in the gold testing sector.

The KrugerRand Checker detects fakes in five coin sizes and three international units. It works with 1 oz, ½ oz, 1/10 oz and ¼ oz Krugerrand, American Eagle, Britannia and Angel coins, as well as British Sovereign. The Fisch tests for common metals with lower densities than gold, while the Ringer detects tungsten, which has a density very similar to gold. Tungsten can be a real threat, so it is important to use both the Fisch and the Ringer together, as the Fisch alone cannot detect tungsten. The wallet set includes both the checker and the ring and is perfect for testing coins without causing damage. Do not let the weight of your coins fool you – use the KrugerRand Checker for peace of mind.

Gold Test Kit 6 Pieces

AuRacle® Electronic Gold Tester

The AuRacle Gold Tester is ideal for small business and medium-sized entities needing to check fine gold percentage purity. It is easy to use and does not require any damaging acids. The tester (SKU: G0080) is the most effective electronic gold tester on the market and can test gold values ranging from 6-24ct. Calibration discs for 14ct or 18ct gold are sold separately and it is important to follow the model specifications when using the tester. Replacement pens, including AGT-1, AGT-2 and AGT-3, are available and fit specific models. The AGT-1 and AGT-3 pens are universal and work across different models.

The Gold Test Kit 6 Pieces offers an affordable way to test gold purity. It includes acid solutions for testing 9ct, 14ct, 18ct and 20ct gold, plus a silver test solution. The kit also features a test stone for drawing lines with both the test gold and reference gold. To use the kit, apply the appropriate acid solution to the lines on the stone. If the test gold line disappears, then the gold is of lower carat than the reference gold. If the line remains, the test gold is of equal or greater value.

Precious Metal Analyser Portable

The XRF Gold Scanner is a portable tool that analyses gold and various alloys, measuring gold, silver, platinum, palladium and more without manual calibration. This method is safer and more accurate than using nitric acid and provides faster and more comprehensive results than fire assay. The scanner can also identify gold-plated items using Thermo Scientific AuDIT™ gold-plating detection technology. It can determine the presence and concentration of alloying elements and dangerous heavy elements that affect the valuation and refining processes.

The Mining Qualifications Authority (MQA) is a Sector Education and Training Authority (SETA) that facilitates skills development under the Department of Higher Education and Training (DHET) and supports mine health and safety under the Department of Mineral Resources and Energy (DMRE) for the mining and minerals sector under

the Skills Development Act (SDA) 97 of 1998 and the Mine Health and Safety Act (MHSA) 29 of 1996, respectively.

De Beers Group names Botswana Olympian as global ambassador

Botswana’s first Olympic gold medallist, Letsile Tebogo, leads an initiative that celebrates his country’s diamond heritage

The De Beers Group has named Letsile Tebogo, Botswana’s 200 m Olympic gold medallist and 2024 World Athletics Male Athlete of the Year, as its global ambassador, marking the start of a unique collaboration that celebrates both his athletic achievements and the transformative power of natural diamonds.

The collaboration builds on Botswana’s remarkable journey over more than five decades to become a world-leading diamond producer, which has – in turn – transformed the prospects of its people. The long-standing diamond partnership between the government of Botswana and De Beers has seen the country use its resource wealth for economic development, while the creation of new opportunities in education and sports has helped cultivate talents such as Tebogo. Like the diamonds that shaped his nation’s future, his rise to excellence highlights Botswana’s latent potential, which – when nurtured –creates something brilliant. This partnership weaves together the story of his sporting achievements with that of Botswana’s development through diamonds, crafting a powerful narrative of possibility, passion and progress.

Reflecting on the collaboration, Tebogo says: “My success story is connected with our nation’s diamond heritage. The very resources that built our schools and sports facilities have paved the way for young athletes like me. I’m humbled that an organisation like De Beers, which has played such a pivotal role in the development of my country, sees fit to play a role in my future too and I’m excited to work with De Beers to highlight the power of natural diamonds for our country and its people. Our partnership goes beyond sport – it’s about showcasing the natural resources driving positive change in our communities and creating pathways for the next generation of Batswana champions.”

“Letsile’s journey from Botswana to Olympic glory mirrors the transformation of natural diamonds. Just as diamonds are shaped by pressure and time, his story embodies the spirit of Botswana’s progress,” says Sandrine Conseiller, CEO of De Beers Brands. “We’re incredibly proud to work with Letsile as we celebrate not only his achievements, but also the remarkable parallel between the realisation of human potential and the journey of a natural diamond.”

The collaboration will involve a series of engagements and media activities focused on celebrating the good that De Beers’ natural diamonds do. As one of the first products of the collaboration, Tebogo will feature as the lead ambassador and central figure in a short film series, Talent Unearthed. Spotlighting athletic talents whose success is deeply connected to Botswana, the series will demonstrate how natural diamonds have uplifted communities and seeks to inspire the next generation of talent using Tebogo’s story of perseverance and dedication. Another key element of the collaboration will see Tebogo and his team identify opportunities for investment in sports development in Botswana. Projects stemming from the collaboration will be launched throughout the year.

The collaboration builds on the De Beers Group’s efforts to showcase the transformative potential of its natural diamonds through engaging and shareable content.

Gems Formed in Magmatic Rocks

Editors: Aaron C. Palke | James E. Shigley

The rigid outer layers of the earth (the lithosphere) are composed of minerals and rocks. Minerals are natural chemical compounds that form in certain geological environments and sets of physical and chemical conditions. In the lithosphere, the main mechanisms for mineral formation are cooling and solidification from igneous magmas, crystallization from high-temperature hydrothermal solutions or vapors, crystallization from lowtemperature aqueous solutions, and solid-state mineral recrystallization during metamorphism. Gem minerals can be formed by any of these mechanisms.

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).

Minerals have specific chemical compositions and arrangements of constituent atoms (i.e., crystal structure). Approximately 5,800 mineral species are currently recognized by the International Mineralogical Association (IMA), most of them rare and narrowly distributed. Despite the variety of mineral species, almost 97% of the earth’s crust is made up of a few elements: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. Hence, the crust is dominated by a small handful of minerals containing these elements (feldspars, quartzes, pyroxenes, amphiboles, and micas). While these

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.

(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).

minerals are occasionally found as gem-quality pieces, most natural gems are rarer mineral phases that fortunately occur in specific deposits as crystals of a size and quality that can be faceted or polished. This edition of Colored Stones Unearthed will focus on gem minerals that form in magmatic environments (figure 1). Other environments of gem formation will be discussed in future columns.

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-

Mineral Formation in Magmas

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

Oceaniclithosphere

Magmatic minerals form during the cooling and crystallization of magmas (molten rock) in certain portions of the earth’s lithosphere and at the surface (figure 2). These magmas vary in chemical composition, but for most the dominant chemical component is silica (SiO2). The amount of SiO2 in a magma dictates many of the properties and eruptive behaviors of volcanic events, and silica concentration can tell researchers a great deal about the geological history of a magma. Basalts, for instance, are silica-poor magmas (typically ~50 wt.%), while rhyolites have high silica contents (typically >70 wt.%). Magmas can form when temperatures rise in the earth and melting of preexisting rocks occurs in the lower crust or upper mantle. Decreases in pressure or the introduction of water or other volatile components can also result in the production of magma deep within the earth. Once formed, magmas can either travel through the crust via fissures, form large magma-filled chambers in other rocks, or be erupted at the earth’s surface through volcanic vents (figure 3).

Profiles on the right show the slab surface and interior temperature during subduction. 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. Poorly understood mechanisms transport some diamonds upward where they can be swept up in kimberlite eruptions and mixed with common lithospheric diamonds (small black diamond symbols). Modified from Smith and Nestola (2021) with carbonated MORB solidus from Thomson et al. (2016b) and DHMS stability field from Harte (2010).

Whatever their origin, the cooling of magmas results in the crystallization of igneous rocks, which are classified according to their texture and mineral composition (table 1). As the magma’s temperature decreases and it

begins to solidify, mineral formation can occur below the surface (to form intrusive or plutonic or phaneritic rocks with coarser grain size due to slower gradual magma cooling). Alternatively, magma that is erupted at the surface will solidify quickly, often leading to small grain sizes of the constituent minerals (to form extrusive or aphanitic rocks) (figure 4).

DHMS phases are a good vehicle for transporting water, with some carrying as much as 10% or more water by weight.

A volcano forms above an underground magma chamber and is created where the magma is vented or erupted at the earth’s surface. Volcanoes occur at specific locations of the crust that are associated with the creation, lateral movement, and then subduction of crustal plates. Most volcanoes are located along boundaries of crustal plates, either at divergent plate boundaries (mid-ocean ridges or continental rift zones where crustal plates separate) or convergent plate boundaries (subduction zones where plates collide). Some volcanoes also occur within crustal plates where they form above “hot spots,” anomalously hot areas of the upper mantle. Below Hawaii, for example, successive islands were created as the crustal plate gradually moved over a thermal feature where magmas were generated (figure 5).

Depending on their chemical composition, silica-poor magmas like basalts are very fluid when erupted (and nonexplosive), and they flow down the gentle slopes

Oceaniclithosphere

Figure 5. The lithosphere—the solid outer portion of the crust—consists of crustal plates that gradually move laterally over geologic time scales due to convection in the underlying molten asthenosphere. Plates form and then separate along divergent plate boundaries. They come together with one plate colliding or being subducted beneath an adjacent plate along convergent boundaries. Slow movement of crustal plates has resulted in the continents changing position relative to one another in the geologic past. Plate collisions produce uplifted mountain ranges along the collision boundary, as in the Himalayas and the Andes, as well as deep oceanic trenches. Most volcanoes are located along mid-ocean ridges and continental rift zones and along subduction zones. Some also occur within crustal plates, where they form above “hot spots” in the underlying asthenosphere. Plate movement over a hot spot can produce a chain of nearby volcanic islands such as those in Hawaii.

When erupted, they form higher steep-sided volcanoes that often produce violent ash cloud explosions or pyroclastic debris flows, depositing the particle material along the margins of the volcano or over the surrounding countryside (e.g., a stratovolcano such as Mount Vesuvius in Italy).

Magmas may solidify underground to form various types of intrusive igneous rock bodies. Depending on size and shape, geologists use terms to describe these rock bodies (all of which may be later exposed at the earth’s surface by geological processes such as folding, faulting, crustal uplift, and weathering; see again figure 3):

• Laccolith (or lopolith): a body of igneous rock that bulges upward or downward

Oceaniclithosphere

Minerals in the crust crystallize from magmas over a range of temperatures (~1300° to ~750°C). Most magmas are silica-based compositions and classified according to their silica content, from silica-poor magmas like basalts (~50 wt.% SiO2) to intermediate magmas like andesites (~60 wt.% SiO2) to silica-rich magmas like rhyolites (>70 wt.% SiO2). Silicate magmas are dominated by oxygen and silicon, and they contain lesser amounts of aluminum, calcium, magnesium, iron, sodium, and potassium as well as rarer elements. Non-silica-based magmas such as carbonatites are much less common and can form only under specific geological conditions.

Carbonated slab melting Hydrous uid

The silica tetrahedron (SiO4) is the basic building block of all silicate minerals. It consists of a central silicon atom bonded to four oxygen atoms that form a tetrahedral arrangement. Silica tetrahedra can also bond to one another by sharing one or more of their oxygen atoms to form more complex tetrahedral arrangements (such as pairs, single or double chains, rings, sheets, and frameworks of bonded tetrahedra; see figure 6). These tetrahedra are further connected by atoms of other elements to form the crystal structures of various silicate

minerals such as olivine, epidote, pyroxenes, amphiboles, beryl, mica, and feldspars, to name a few.

Several geologic factors influence the evolution of magma composition and crystallization. These include the initial composition of the magma source, the presence of volatiles such as water or elements like fluorine in themagma, partial melting of rocks at the source, interaction with melted or unmelted (restite) minerals, interaction with or assimilation of wall rocks, mixing of magmas, separation of magmas into immiscible melts, loss of volatile phases (degassing), fractional crystallization of minerals, and accumulation of earlyformed minerals. As a result of these factors, the overall composition of the magma, and the minerals that crystallize from it, changes over time. Common silicate mineral formation takes place from the magma at progressively cooler temperatures in a specific sequence. This sequence is schematically described by Bowen’s reaction series (figure 7). This reaction series illustrates the differences between minerals that typically crystallize from magmas at high temperatures (e.g., olivine, pyroxenes, amphiboles, micas, and calcium-

rich feldspar) and those that typically crystallize at lower temperatures (quartz, micas, and potassium-rich feldspar). If early-formed minerals are separated from a magma, the removal of those components changes the composition of the remaining magma, generally leading to more silica-rich compositions (figure 8). Bowen’s reaction series can also be considered from the bottom up in that the lower-temperature minerals at the bottom of the diagram are also the first to break down during partial melting. The presence of silica-rich minerals like quartz, micas, and potassium-rich feldspar at the bottom of the diagram demonstrates that the early-formed magmas during partial melting tend to be silica-rich. Removal of such partial melts can produce rhyolitic magmas. Magmatic rock environments are also important sources for ore deposits—economic and minable concentrations of gold, silver, copper, nickel, platinum, chromium, vanadium, cobalt, and other elements that are not found in large amounts in most silicate minerals. Hydrothermal and pegmatitic deposits of gems, although related to magmatic activity, will be discussed separately in future editions of this column because of their importance for certain gem deposits.

Figure 7. Based on field observations and experimental studies, geologists in the early 1900s began to recognize that the common silicate minerals form at specific temperature ranges from a cooling magma. This sequence of crystallization is known as Bowen’s reaction series, named after geologist Norman L. Bowen. Higher and intermediate temperatures are associated with mafic and intermediate magmas, while lower temperatures are associated with felsic (silicarich) magmas. At higher temperatures, the sequence has two branches. The continuous branch describes the evolution of plagioclase feldspars from calciumrich to more sodium-rich. The discontinuous branch describes the sequence of formation of different minerals as temperatures decrease. Although geologists now recognize some exceptions, this concept is still accepted as the general model of silicate mineral formation from cooling magmas.

Figure 8. With the cooling and solidification of magmas, mineral formation proceeds in a series of steps illustrated by the discontinuous branch of Bowen’s reaction series in figure 7. These simplified diagrams illustrate stages of fractional crystallization of common minerals from a silicate magma. If the starting magma is ultramafic or basaltic in composition (A), during cooling it changes in chemical composition as different minerals form in sequence from the melt. In these diagrams, olivine crystallizes first (stage 1), followed by olivine and pyroxene (stage 2), pyroxene and plagioclase feldspar (stage 3), and finally plagioclase feldspar (stage 4). These crystals are separated from the melt as layers at the bottom of the magma chamber, and the remaining magma (B) gradually becomes more silica-rich (more viscous). The remaining magma becomes depleted in elements that were incorporated in the earlier-formed minerals, and it is enriched in elements that were not easily accommodated in these minerals. Modified from Johnson et al. (2017).

Gem Mineral Formation from Magmas

Magmatic gems form either by crystallization of the magma at depth or at the earth’s surface, and occasionally in rock cavities from a gas phase (a vapor) released during magma cooling. Magma eruptions can also bring up mineral crystals or fragments of deeply formed crystals or rocks (including some gem minerals) derived from other sources—geologists refer to them as xenocrysts or xenoliths

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-

Diamond-bearing kimberlite eruption

When exposed at the surface, igneous rocks often weather and decompose to form smaller particles. Resistant minerals (such as diamond or corundum) can remain in the sedimentary environment and become concentrated in secondary alluvial deposits by the movement of water. Such deposits are sources for several important gem minerals. Over time, long-distance water transport of gem crystals also can winnow out fractured crystals: Those that survive the journey can be waterworn but of higher quality. Although gem mineral formation from magmas is the subject of this column, some of these same minerals can also form by other geological processes such as metamorphism.

Diamond. Most gem diamonds formed between 1.0 and 3.5 billion years ago and at depths between 150 and 250 km in the lower crust and upper mantle (and in some cases in the lower mantle as deep as 800 km; see Smith et al., 2017). It is now understood that their formation took place

from carbon-containing fluids, based on studies of tiny inclusions of minerals and fluids found within diamonds, although the details of this growth process are still the subject of geological study. Once formed, the diamonds were carried to the earth’s surface by eruptions of kimberlitic or lamproitic magmas (figure 9). Deeply formed diamonds were slowly transported upward by convection in the mantle to a depth where they could be caught up in erupting igneous magmas. Diamond formation was described in more detail by Shirey and Shigley (2013) and by Smit and Shirey (2018, 2019). At the surface, diamonds

Opals contain up to 20% water and if exposed to extreme heat or dryness, they can lose moisture and crack – a process known as "crazing". Some jewellers recommend storing opals with a small dish of water to maintain their hydration.

Legend has it that former President of South Africa, Paul Kruger, hid a fortune in gold before fleeing the country during the Anglo-Boer War. The socalled "Kruger Millions" have never been found and treasurehunters are still looking for them

Some of the finest watch dials are made used Grand Feu (Great Fire) enamel, a technique where powdered enamel is repeatedly fired at over 800̊ C.

Early South African miners discarded platinum as an unwanted by-product of gold mining, not realising its value. It was not until the 20th century that platinum became a highly sought-after metal.

In some ancient battles, warriors used garnet as an alternative to metal in bullets, believing the red stone would cause more damage.

Mining in Africa has long been a cornerstone of economic development on the continent, but discussions about the sector often focus on large-scale extraction. However, a shift in perspective is gaining traction – one that highlights the importance of downstream industries in shaping a more sustainable and value-multiplying sector

Driving mining’s full potential beyond extraction

Beyond raw material exports, businesses involved in refining, processing, logistics and supply chain integration are proving essential to unlocking mining’s long-term economic benefits. According to the African Development Bank, Africa is home to 30% of the world’s mineral reserves, yet much of its economic benefit is lost when raw materials are exported without value addition. The move toward beneficiation, processing and mining-related services is increasingly recognised as a way to capture more value locally, while supporting sustainable industrial growth.

“As we engaged with more of our SME clients at this year’s Mining Indaba, we realised that there was a lot of work to be done through collaborative efforts, which could result in great value for South Africa by appropriately supporting the downstream services environment that exists in this sector,” says Abe Andries, Head of Mining at Business and Commercial Banking, Standard Bank SA.

Mineral-rich economies across the continent are placing greater focus on the transformation of raw materials into refined products, supply chain efficiencies and infrastructure investment to support these industries. Strengthening these areas is seen as key to enhancing Africa’s role in global trade and ensuring that mining delivers a lasting economic impact.

In SA, the mining sector contributed an added value of approximately R202,05 billion to gross domestic product in 2023. Across the continent, the African Continental Free Trade Area is projected to boost intra-African trade in processed and refined minerals, creating more opportunities for local industries.

Despite this potential, businesses involved in logistics, beneficiation and processing continue to face challenges in access to capital and trade finance. Strengthening financial ecosystems, expanding trade facilitation and integrating digital banking solutions are seen as crucial to ensuring that these businesses can scale.

A well-functioning mining sector is one in which businesses across the value chain have access to the right financial tools, trade platforms and strategic partnerships. With mining operations spanning multiple countries, the ability to efficiently move products across borders and into industrial sectors is a critical factor in long-term sustainability, as a McKinsey report reveals.

“The downstream mining sector is a vital driver of Africa’s economic transformation. Beyond extraction, businesses that refine, transport and supply the industry enable job creation and industrialisation, as well as stronger trade ties. As a bank, we’re committed to supporting these businesses by providing relevant and targeted products and solutions that help them start, manage and grow their operations. Through our deep understanding of

“Beyond extraction, businesses that refine, transport and supply the industry enable job creation and industrialisation, as well as stronger trade ties.”

the mining value chain and the industries that power it, at Standard Bank we turn possibility into opportunity for the vibrant businesses driving Africa’s economy,” says Andries.

Financial institutions play a key role in supporting and providing financing solutions tailored to the needs of businesses across the mining value chain. Access to structured trade finance, working capital and crossborder payment solutions allows businesses to expand, invest in sustainable operations and integrate into global supply chains. In an increasingly digital world, financial technology and digital banking platforms are also enabling mining suppliers, refiners and logistics companies to operate more efficiently, manage liquidity and navigate international markets.

Africa’s mining sector is evolving, with industry leaders, policy-makers and businesses alike increasingly focused on how to capture more value within the continent, rather than simply exporting raw materials. Greater collaboration between privateand public-sector players is expected to shape a more integrated and competitive mining value chain, benefitting not only mining majors, but the businesses that process, supply and sustain the sector.

A key insight derived this year from Standard Bank’s many engagements with clients is that in order to provide world-class financial services to mining businesses in the SME market, its deep understanding of the sector is essential. It is therefore committed to getting closer to those clients and deepening its knowledge of the SME segment of mining and its intricacies.

With global supply chains shifting and Africa positioning itself as a leader in mineral beneficiation and trade integration, ensuring that the downstream market is fully integrated into industry decision-making is becoming an increasingly important conversation.

The growing momentum behind beneficiation, sustainability and local supply chain development highlights the opportunity for mining to become not only an extraction-driven sector, but a long-term driver of industrial and economic growth.
