Coloured Diamonds

Natural coloured diamonds are some of the world’s rarest commodities. Unlike white diamonds which still exist in nature in large quantities, fancy colour diamonds constitute less than 1% of the quantity of rough diamonds manufactured globally, every year, and this quantity is steadily shrinking.

In order to classify diamonds as natural loose coloured diamonds, they are certified in a gemological institute such as GIA, HRD, or IGI .

The price of a natural loose diamond is affected by the 4Cs: Colour, Cut, Clarity, and Carat. Fancy loose colour diamonds (unlike white diamonds) are polished in a different manner than white diamonds. This is done in order to emphasize the colour as much as possible.

Fancy loose colour diamonds can appear as one primary colour, without any secondary hue - for example, fancy blue diamonds, fancy pink diamonds, etc. When it appears as a single colour, the price of the diamond will be considerably more expensive than a diamond with a secondary hue - for example, fancy Brownish Greenish Yellow, fancy Orangey Pink, or fancy Grayish Blue.

The intensity grading system for fancy colour diamonds differs than that of white diamonds. Unlike white diamonds, which range from the letter D-Z, fancy colour diamonds are graded by Light, Fancy Light, Fancy, Fancy Intense, Fancy Deep, Fancy Dark, and Fancy Vivid. The stronger the colour - the higher the price.

Pink diamonds are the world's most desirable of all the fancy colour diamonds, and most of the loose pink diamonds are originally from the Argyle mine in Australia. Every pink diamond discovered in the Argyle mine receives a laser inscription. Our selections include fabulous pink diamonds from the Argyle Mine in Western Australia. Highly prized and collectable, Argyle pink diamonds are rare treasures - worn, admired and loved by a fortunate few. What's more, with the Argyle Mine expected to close within a decade, these exquisite gems are becoming increasingly sought after.

No one knows for sure how pink diamonds are coloured, but it is believed it is as a result of pressure beneath the Earth's crust. As pressure raises the diamond closer to the surface, it is believed that its structure becomes altered, thus absorbing light and producing colour.

What is known is that from one hundred miles deep within the Earth's surface comes the treasure that is the pink diamond. It is so remarkable that nothing compares to its colour and brilliance, and it is substantially more valuable than its white diamond equivalent.
