Diamond Colour Grading Scale
Colour is the grading scale that describes a white diamonds colour quality. It starts from "D" which is the best and most expensive, and goes all the way to "Z". We recommend starting at an "F" colour, as D, E and F diamonds are all in the top "colourless" scale and don't have any hints of yellow or brown. You can consider G, H, and I colour diamonds if your budget is constrictive. Fancy coloured diamonds have a different scaling system altogether.
