COLOR GRADING REPRESENTS A FUNDAMENTAL ELEMENT OF A DIAMOND.
Most diamonds fall into the D-Z color scale which represents the lack of yellow or brown in the diamond. ‘D’ color is the whitest diamond , and ‘Z’ being the most yellow in the regular scale(After ‘Z’ we reach the ‘Fancy’ colored diamonds). The most valuable diamond in this scale is the white ‘D’ color. Generally, as we go down the scale the value of the diamond drops until we reach the ‘Fancy’ range.
There are several reasons as to why the value of the diamond changes according to its color. One obvious reason is taste and preference. White diamonds strike our eye with more brilliance, making them the highest in demand. Another reason is the elements traced within the diamond. During a diamond’s formation, various elements and particles are captured. The most common element present in a diamond is Nitrogen, which normally reflects yellow or brown colors. The lower the presence of this element, the less yellow the diamond appears, and therefore is more valuable.
