A diamond's color is important to its value. The rarer the color, the more valuable the diamond.Speak With a Specialist
Diamonds naturally come in every color of the rainbow but the most common are those with a slight yellowness. The colors of the most common diamonds are ranked on a scale from D (absolutely colorless) to Z (naturally yellow).
The rarest and most expensive diamonds are either D-colorless or of a natural fancy intense color such as blue, yellow, pink, or the most rare, red. However, not all colored diamonds are natural; some are treated with harmless radiation to artificially enhance color. These diamonds are significantly less valuable than natural colored diamonds because they are not as rare. A diamond’s color should be determined when it is “loose” or not in a piece of jewelry yet. This is because the color of the jewelry can play visual tricks on the human eye making a diamond appear more yellow in yellow gold or whiter in platinum.
