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.
