The most important factor when evaluating a Colored Diamond is the intensity of the color. The more intense the color, the more valuable the diamond is. The grading scale for Fancy Colored Diamonds is: "Faint", "Very Light", "Light", "Fancy Light", "Fancy", "Fancy Intense", "Fancy Deep", "Fancy Vivid".
Diamonds are also sometimes found in 'fancy' colors: pink, blue, green, yellow, brown, orange, and, very rarely, red. These diamonds, called 'fancies' are incredibly rare and valuable.
Colorless diamonds are extremely rare, and therefore very valuable. Diamonds are graded on a color scale established by the Gemological Institute of America (GIA), ranging from D (colorless) to Z.
The Fancy Colors extend beyond the GIA colour grading system.
Diamonds were formed under intense heat and pressure. Colorless diamonds are composed of pure carbon. Traces of other elements incorporated into their atomic structure account for the variances in color. A single change in color grade can significantly affect a diamond's value.
