What does the GIA color grade D represent?

Explanation:
GIA color grading looks at the diamond’s body color under controlled lighting and a white background, rating how colorless the stone appears. The scale runs from D to Z, with D at the top. A diamond with no detectable color is considered colorless, making it the highest grade on this color scale. If any tint such as yellow or brown is evident, the diamond would receive a lower grade, not D. Iridescent isn’t a color grade in this system, so it doesn’t describe the diamond’s color grade. So, D means colorless and represents the highest color grade.
