Diamond Color

The color of a diamond is one of the factors that affects its price. White diamonds should be as white as possible. Colored diamonds should display their color as richly as they can. The prices of diamonds at the two extremes in the spectrum are far higher than the prices of diamonds in between. This is because colorless diamonds and richly colored diamonds (naturally colored without enhancements) are the rarest diamonds of all. The price of the diamond is tagged to its rarity.

Because the value of a diamond is related to its color, diamonds are sometimes treated to improve their color. Yellowish or brownish diamonds are turned into fancy colored diamonds through irradiation and heat. These can be made into green, bright yellow, purple or red fancy colored diamonds. Unlike natural fancy colored diamonds, these can be obtained at bargain prices. Buy these treated diamonds only because you like them, not because you think they are good investments because they are not.

Colorless diamonds are valuable while brownish diamonds are not. Hence High Pressure High Temperature treatments HPHT are used to turn brownish diamonds colorless and the results are permanent. If a diamond is treated via HPHT, the Federal Trade Commission requires that this be disclosed. Treated diamonds are worth less than natural diamonds, all things being equal.

The colorless diamonds, are D, E and F. D being the best color possible.

The next best colors are G, H, I and J which are nearly colorless. Colors D through J are used in Jewelry.

Colors K, L and M are faintly tinted.

The colors get more obvious as the grades progress down to Z.
