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.

Does Diamond Colour Matter? 

Colour is the second most important of the 4Cs because the colour grade directly affects the stone’s appearance. Diamonds with a poor colour grade can appear slightly yellow instead of the desired brilliant white. Additionally, the Tiffany Gemmological 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 jewellery from Tiffany, you’re buying a piece of artwork.”
