Diamond color varies from D to Z, with D containing the least and Z - the most color. It is not the color, but rather the lack of color that distinguishes a high-quality diamond. The most valuable diamonds are the ones with the least color. Toxsur jewelry features diamonds with the highest grades of color.


D - is the highest color grade; absolutely colorless and a very rare diamond.


E - is a very high color grade; colorless and a rare diamond.


F - is also a very high color grade; colorless, but very slight color can be

     detected by only an expert gemologist.


G, H - is a high color grade; near-colorless diamond.


I, J - near-colorless and color is slightly detectable.


K-Z - not carried by Toxsur; these diamonds have noticeable color.
