Rarer than a colorless diamond, fancy colored diamonds are some of the most striking gem that can be found today, offering brilliance and color together in a way nothing else can. Fancy colored diamonds are created when tiny amounts of trace elements react with the carbon atoms as the diamond is being formed under immense pressure, permanently altering the color of the entire diamond.
With just a one in ten thousand chance of a diamond having any natural color, and much, much lower chance of a vibrant fancy color that we love, these incredibly special diamonds will always be a rarity. While in the colorless diamonds, the less color is visible the more valuable the diamond, in the fancy colored diamonds it is the opposite, the stronger the color, the rarer and more valuable the diamond. The intensity of the color measured on a scale for valuation purposes. And goes from pale to the most intense, with the classifications being:
Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid/Fancy Deep/Fancy Dark.
You can find fancy colored diamonds in almost all colors of the rainbow, with yellow and brown being the most common, followed by pink and blue, while orange, red, purple and green and the rarest colors to be found. How we describe the colors is the other aspect of fancy colored diamonds, and this is done by using the primary color hue. However, some diamonds have secondary colors, tints that show in reflected light, and these would be described as for instance reddish-purple, indicating a purple diamond with a red hue. Diamonds with no tint are described as pure.
