Diamond Color Chart
Tiffany only accepts engagement diamonds in the “colorless” and “near colorless” range on a diamond color scale. In other words, for engagement rings, Tiffany only accepts D color diamonds, E color diamonds, F color diamonds, G color diamonds, H color diamonds and I color diamonds. Borderline diamond color classifications are automatically given the more conservative grade.

Does Diamond Color Matter?
Color is the second most important of the 4Cs because the color grade directly affects the stone’s appearance. Diamonds with a poor color grade can appear slightly yellow instead of the desired brilliant white. Additionally, the Tiffany Gemological Laboratory will not accept stones exhibiting strong or excessive fluorescence, which, in natural lighting, can give diamonds a milky appearance.
“If you’re buying a piece of jewelry from Tiffany, you’re buying a piece of artwork.”
