Fancy yellow diamond
A diamond’s yellow color is the result of nitrogen molecules absorbing blue light, making the diamond appear yellow (yellow is the complement of the color blue). While in rough form, a natural yellow crystal is usually cut into a large and a small stone. Larger stones feature a much more intense yellow than smaller cuts.
Faint, very light and light yellows are not considered fancy color diamonds; they are graded on the “D-Z” color grading scale, generally at the lower end of the scale.
