Only one in every 10,000 diamonds possesses natural colour and is referred to as a fancy colour diamond. For this reason, fancy colour diamonds are purchased almost exclusively for the intensity and distribution of the diamond's colour. Criteria considered when purchasing a white or colourless diamond, such as cut proportions and clarity, are less important when purchasing a fancy colour diamond.
The information below will help you understand fancy colour diamonds to determine the diamond that's right for you.
Colour intensity, the deepness or richness of colour, is the most important consideration when purchasing a fancy colour diamond. The more intense the colour, the rarer and more valuable the diamond will be. Fancy colour diamonds are graded in order of increasing intensity from Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Dark, and Fancy Deep.
All of our Blue Nile fancy colour diamonds possess natural colour and are never exposed to artificial colouring techniques such as dyeing or irradiation.
After colour grade, carat weight has the most impact on price for fancy colour diamonds. When diamonds are mined, large gems are discovered much less frequently than small ones. This makes large diamonds much more valuable. For this reason, diamond prices for fancy colour diamonds rise exponentially with carat weight. Learn more about carat weight in our Diamond Education section.
Due to the nature of fancy colour diamonds, clarity is less important than it is in their colourless counterparts. This is true because inclusions tend to be masked by the diamond's colour.
Fancy colour diamonds are primarily cut to emphasise their colour. This contrasts with colourless diamonds that are cut to maximise sparkle or brilliance, which in some instances can detract from the natural colour of a fancy colour diamond. While fancy colour diamonds still exhibit brilliance, colour is the most important characteristic considered when they are being cut.
While cut describes a diamond's light performance, dimensions and finish; shape refers to the overall outline of the diamond when viewed from the top (e.g. round, princess or marquise). It's important to note that many fancy colour diamonds are cut into non-traditional shapes to enhance their natural colour. Due to the rarity of fancy colour diamonds, a specific shape in a specific colour may not be available at any given time.

All Blue Nile fancy colour diamonds are independently analyzed and graded by the Gemmological Institute of America (GIA), which is among the most respected laboratories in the diamond industry. Each diamond is accompanied by a coloured diamond identification and origin report. This authoritative report lists the diamond's specifications including its colour grade, and ensures its natural origin.
Setting Fancy Colour Diamonds
When choosing a setting for a fancy colour diamond, it is best to choose a setting material that will enhance the natural colour of your diamond. For example, fancy yellow diamonds are often set in yellow gold, while pink diamonds look best when set in rose gold.
