Regarded for their exquisite beauty and the timeless qualities of love and devotion that they represent, diamonds have fascinated mankind throughout the centuries.

Coloured diamonds are the world’s most concentrated form of wealth. A coloured diamond portfolio fits inside an envelope and can easily be transported in your coat pocket. They can be transported quietly and legally, and sold globally in most major cities. These facts alone make coloured diamonds worthy of consideration by individuals seeking discreet investment opportunities. Prices for the highest grades of coloured diamonds have increased in value by an average of between 15-25% per year, with rarer colours and higher grades enjoying the greatest appreciation. In addition, this appreciation has statistically been noncorrelated to the stock and bond markets, an important consideration for investors seeking a diversified portfolio.

A Coloured diamond should be viewed as a midto-long term investment. With demand for coloured diamonds continuing to grow and supply becoming very scarce, experts predict prices will significantly outperform the historical averages over the next five years.

Why Invest In Coloured Diamonds? Fancy coloured diamonds have a rock solid history of steady price appreciation and they are expected to continue increasing in value over time.

“Diamonds could very well outperform base metals in the coming years�

Over the past 30 years the price of coloured diamonds has remained strong; in fact the price of investment grade coloured diamonds has steadily increased by approximately a minimum of 15-25% per year with some diamonds above a certain carat size showing in excess of 45%

Without question, fancy coloured diamonds are truly rare and exotic; people derive much personal pleasure and satisfaction from simply owning something so unique. The rarity of fancy coloured diamonds has taught investors that they are recession proof. Over the decades and especially during times of great economic uncertainty investors have learned that fancy coloured diamonds provide a reliable store of wealth. Past performance shows that in both national and global recessions over the past 30 years investment grade diamonds have sustained their value and have continued to increase.

As an heirloom, fancy coloured diamonds can easily be passed from one generation to the next. The unique and rare nature of fancy coloured diamonds means their value is unconnected to and unaffected by the trials and tribulations put upon other forms of investment, including the stock market. When there are so many other forms of comparatively high risk investment opportunities to provide capital growth, investing in fancy coloured diamonds provides a relatively low risk hedge against any losses that may be incurred by investing in other alternative assets or financial products over the medium to long term.

They provide a hedge against inflation. They have universal appeal with an internationally recognised system of standards. Easy investment options are available. Can be used as jewellery and enjoyed as the investment matures. They offer high portability, complete privacy and ownership. They’re a natural resource, hence available in limited supply.

Prices of coloured diamonds are not highly correlated to other traditional investment assets such as stocks and bonds. It is also independent of government laws; coloured diamonds retain their value even during recessions and their price volatility is lower. Naturally fancy coloured diamonds are the most valuable gemstones on the planet as determined on a price per carat basis. Exceptionally fine coloured diamonds have no fixed price and as with fine paintings, set rules do not apply. Their true value will be determined when they are sold at auction.

“Investors are snapping up diamonds as hard assets in order to hedge their portfolios. Many investment consultants are recommending diamonds as ‘must have’ asset for a secure investment portfolio”

“The market for fancy coloured diamonds is truly an arena in which collectors do battle to possess these ultimately rare and spectacular objects. The number of these stones available at any one time is so small, that statistics cannot be applied, and the price of every stone is as unique as the object in question...�

Understanding Diamond Grading A diamond’s cost is based on the characteristics known as the “4 C’s”. Clarity, Colour and Cut (proportion) are the quality elements which together with the Carat Weight determine the value of a stone.

While clarity is frequently assumed to be the most important factor of all the “C’s”, in fact, colour and cut have a more profound effect on the visual appearance of a diamond.

The closer a diamond grades to the left of one or all of these scales the rarer and the more costly it will be.

Carat Weight


Carat is the unit of weight for all gemstones. one carat is subdivided into 100 “points”. Therefore a diamond measuring 75 points is 3/4 carat in weight, or 0.75ct. There are five carats in a gram.

Cut, sometimes the forgotten “C”, ensures that a given stone has maximum brilliance and sparkle which would not be the case were the stone cut for weight alone.

The word “carat” comes from the seed of the carob tree pod which is found in tropical climates. These seeds were used until this century to weigh precious gems.

Simply put, when looking at a diamond, if it doesn’t catch your eye or if it doesn’t flash in the light, it’s probably not well cut. Good cutting is what brings fire to the ice.

Clarity A diamond’s clarity is determined by the number, nature, position, size and colour of internal characteristics called “inclusions” and surface features called “blemishes”. Clarity is measured on a scale ranging from pure (flawless) to heavily included (I-3)

Colour Increasing degrees of body colour are measured on a scale ranging from no colour at all (d) to deeply coloured (Z). Beyond “Z” is the range where the diamond’s colour is vivid and rich, called “fancy colours”.
