“Colorless” or “white” diamonds – the diamonds traditionally used for engagement rings, stud earrings and solitaire pendants – are evaluated on a color-grading scale developed by the GIA. It spans the alphabet from D to Z with D being colorless, and Z representing a light yellow tint. With colorless diamonds, the value is placed on how little color you can see, and this is determined by studying the diamond under controlled lighting and comparing it to the GIA’s color scale. Incidentally, D-grade diamonds – that is, truly colorless diamonds – are extremely rare and valuable.
GIA Color Range
Diamonds with a color grade of D, E or F are considered colorless.
Diamonds graded G, H, I and J are near colorless.
Diamonds that fall in the K-M color grade range have a faint yellow tint. Diamonds in the N-R range have a very light yellow tint and S-Z are light yellow.
All loose diamonds available on Diamond.com fall into the D – J (colorless to near colorless) range.
