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