Over 90% of all gem diamonds have a basically yellowish color. The intensity can vary from nearly colorless, which is preferable, to decidedly yellow. The value of a white stone is higher than that of a yellowish stone. However, diamonds can also have a distinct orange, brown, pink, green or blue color. These color diamonds can be extremely valuable.
The color grade describes the color tones in a stone. D is perfectly colorless, which is rare and expensive. The color scale goes from D to Z and indicates yellow and brown tones. It takes a trained eye to distinguish between shades that are close together, but an untrained eye see the difference between shades that are several tones apart with a little practice.
D Colorless – Highest color grade your diamond can achieve. This color emits unequaled brilliance, and is extremely rare.
E Colorless – Only extremely small traces of color can be identified by an expert gemologist. Also extremely rare.
