The less color a diamond has, the more valuable it is. Part of this has to do with how much “fire” the diamond exhibits. Acting as a prism, a diamond can divide light into a spectrum of colors and reflect this light as colorful flashes called fire. Just as when looking through colored glass, color in a diamond will act as a filter, and will diminish the spectrum of color emitted. The less color in a diamond, the more colorful the fire, and the better the color grade.

Diamonds are found in nature in a wide range of colors, from completely colorless (the most desirable trait) to slightly yellow, to brown. The diamond color grading system uses the letters of the alphabet from D through Z, with ‘D’ being the most colorless and therefore the rarest and most valuable, and ‘Z’ having the most color within the normal range, and being the least valuable, all other factors being equal. A diamond’s color is determined by looking at it under controlled lighting and comparing them to the Gemological Institute of America’s color scale, which is based on a set of diamonds of known color. Here is a diagram showing how a diamond’s color is graded:

Carat color Scale

Diamonds found in nature come in colors ranging from colorless to more rare and costly pink, green or blue stones (commonly referred to as ‘fancy’ diamonds).

A diamond’s color also has a great impact on its cost. Since ”colorlessness” is the most sought-after trait in terms of color, diamonds that are higher up on the color scale (e.g. D, E, F) will have a greater value.
