Diamonds are available in many colours. They are classified as white, practically colourless diamonds, or fancy colours. Diamond colour distinctions are so subtle that only a trained gemologist can colour grade the gem. A diamond's price value can rise or fall based on the intensity and hue of the colour.
The Diamond colour grading scale ranges from D to Z.
D, E, F : colour-graded diamonds are colourless diamonds but not always of the best value.
G, H, I : colour-graded diamonds are also clear and have the perfect balance of quality and value.
J, K, L : diamonds have a slightly warm tint and are sometimes considered diamonds of value depending on other factors.
M to Z : diamonds have a noticeably yellow, brown or blue tint.
