Coloured Diamonds
Select a diamond from the thousands of certified coloured diamonds in our collection.
Coloured diamonds, also known as 'fancy diamonds', are a stunning type of natural diamond available in an array of colours and tones. In the world of diamonds, rarity undoubtedly equals value, and fancy coloured diamonds are far rarer than traditional white stones.
With only one in 10,000 diamonds having a fancy colour, it's clear why many experts consider natural fancy coloured diamonds to be the most highly prized of gems. Coloured diamonds boast dazzling brilliance and are available in several exquisite colours, from popular pinks and yellows to the rarest green, blue, orange and purple hues.
There are 12 colour variations of natural coloured diamonds and over 90 secondary hues, nine intensity levels, and more than 230 colour combinations. The rarest and most valuable are red, green, purple and orange — followed by blue and pink. Yellows and browns are the most common.
Natural Fancy Coloured Diamonds
Colourless diamonds are valued upon their absence of colour using GIA's D-to-Z colour-grading scale, decreasing in value as the colour becomes more obvious. Fancy diamonds are the opposite — their value increases as the depth of colour intensifies.
Fancy coloured diamonds exhibit colour beyond the Z range, with vivid fancy coloured diamonds extremely rare. Black, grey, and fancy white are also recognised variations. Perhaps the most famous coloured diamond is the 'Black Orlov' or 'Eye of Brahma' — a 67.50-carat cushion-cut black diamond.
When you buy coloured diamonds, large vivid coloured stones are the most valuable as they are so difficult to obtain. Available coloured diamond hues include yellow, pink, blue, red, purple, grey and black.
Features and Grading of Natural Coloured Diamonds
Grading natural fancy coloured diamonds is a specialised and complex task — coloured diamonds come in so many shades that there are simply too many variations to make a complete set of master stones. The GIA uses a combination of comparison stones and printed standard colours to accurately identify a diamond's characteristic colour.
Once the diamond's characteristic colour has been determined, it is assigned a colour grade signifying colour intensity:
- Faint · Very Light · Light
- Fancy Light · Fancy · Fancy Intense
- Fancy Vivid · Fancy Dark · Fancy Deep
Intensity refers to how deep the colour is — higher intensity coloured diamonds are rarer and more valuable. All Rêve Diamonds coloured diamonds are accompanied by an official GIA report.

FAQs
What is a fancy coloured diamond?
Natural fancy coloured diamonds are rare specimens that exhibit colour beyond the Z range of the GIA colour grading scale. The characteristics used to describe their colour are hue, tone and saturation. Coloured diamonds come in almost any colour imaginable, with red, green, purple and orange being the rarest, followed by pink and blue. Yellows and browns are the most common fancy colours.
Are fancy coloured diamonds real?
Yes, natural coloured diamonds are completely authentic. The colours exhibited by these stones have developed in nature over millions of years, formed when other elements interact with carbon atoms during a diamond's creation. Nitrogen, boron and radiation can all affect the colour of a natural diamond.
Are fancy coloured diamonds more expensive?
Natural coloured diamonds are more expensive than white diamonds due to their rarity. Intense or vivid diamonds have a strong colour and a much higher value than white diamonds of a similar size and clarity. Coloured diamonds range in price from thousands to millions of pounds, with value depending on carat weight, cut, clarity and colour.
What is the rarest coloured diamond?
Red diamonds are the rarest fancy coloured diamonds, with only 20 to 30 natural red diamonds known to exist. If you want to buy natural red diamonds, you'd have to pay in excess of one million dollars per carat.
Are fancy coloured diamonds a good investment?
