Diamond Color Grades Diamond color is the measure of a diamond's degree of yellow or brown. Colorless is the most desired of diamond colors, with other grades exhibiting increasing degrees of tint. So... the best color (and the most expensive) is actually no color at all. A few, very rare diamonds exhibit other "fancy" colors, such as purplish pink, green, blue, intense yellow, champagne, cognac, etc. IMPORTANT: Color is something you have to see to understand the subtleties, so you will need to rely on a good jeweler to show you. We rated the top internet jewelers and created an exclusive network of the top local jewelers in most major areas -- so you would have somewhere to turn when you need help.
