Color
In nature, the absence of any color is very rate as most diamonds contain tiny amounts of nitrogen. The untrained eye may not be able to detect these minute variations of color, but these distinctions affect the rarity and ultimately the value of your diamond. De Beers subjects all the diamonds it uses to a customary color examination, regardless of any previous evaluations.
The color of every De Beers diamond is skillfully determined by the De Beers Institute of Diamonds. We compare every diamond to a De Beers Ideal Master diamond. Color is then rated according to a precise scale, running from “D” (colorless) to “Z” (saturated). If a stone has a borderline color classification, we assign it the lower rating. Past “Z” a diamond’s color is considered “fancy.” Fancy colored diamonds are very valuable and, correspondingly, are graded by very different parameters.
