Color Grade D Diamond (Absolutely Colorless)

Diamonds composed of pure carbon are colorless. A "D" Color Grade diamond is absolutely colorless and is the highest Color grade a diamond can achieve. This color emits unequaled brilliance, and is extremely rare. Many systems have been used to grade diamond Color. To eliminate confusion, the Gemological Institute of America (GIA) introduced a Color grading system in the 1950s that is used today by the entire diamond industry. The scale begins at D (colorless) and ends at Z (light yellow). The scale starts at D because that letter had not been used previously to classify Color.

Diamond Color is difficult to discern when a diamond is viewed face-up. Therefore, the grader turns the diamond facedown against a pure white surface under carefully controlled light. The diamond grader compares the diamond to a so-called master stone to determine Color. A master stone is a diamond of a predetermined Color that is used for comparison.

Listed below is a standard Color grade chart demonstrating the Color range from D to M.
