NATURAL FANCY PURPLE COLOURED DIAMONDS

Coloured diamonds – also referred to as “fancy diamonds” – are a rare and mesmerising type of natural diamond found in a spectrum of remarkable shades. In the world of diamonds, rarity often determines value, and fancy coloured diamonds are far less common than traditional white diamonds.

Only around one in every 10,000 diamonds naturally develops with a fancy colour, making them some of the most prized and sought-after gemstones available. These diamonds occur in a wide variety of colours – from popular pinks and yellows to the exceptionally rare blues, greens, oranges, and purples.

Unlike colourless diamonds, which are valued for their lack of colour (graded on the GIA’s D-to-Z scale), fancy coloured diamonds become more valuable as the depth and vibrancy of their hue increases. These diamonds sit beyond the Z scale, with the most vivid examples being especially rare and valuable.

There are 12 primary colour categories, over 90 secondary hues, nine intensity levels, and more than 230 potential colour combinations. Many fancy coloured diamonds have blended tones due to secondary hues such as grey, brown, or pink. The most desirable diamonds are those with rich, vivid colouring, strong saturation, and minimal dilution.

Among these, natural fancy purple diamonds stand out for their romantic allure and intriguing formation. While generally rarer than black or yellow diamonds, high-quality purple stones with deep, even colouring are among the most collectible and visually striking.

One of the most well-known examples of a purple diamond is the “Royal Purple Heart” – an exquisitely cut, 7.34-carat fancy vivid purple diamond celebrated for its symmetry and intensity.
