GIA cut grades apply to standard, round brilliants in all clarities across which color range?

• A. A to M
• B. G to Y
• C. D to Z
• D. I to P

Answer: (C)

GIA cut grades are defined for standard round brilliants across the color range from colorless to light yellow/brown. In diamond color terms, that spans from the top of the scale down to the lighter end, commonly described as D through Z. This means cut grades are applied to diamonds anywhere from colorless through the lighter tints, but not to diamonds outside this range (fancy colors). So the range that fits GIA’s standard practice is the full D-to-Z span. The other options represent portions or outside parts of the color scale and aren’t the official range for applying GIA cut grades.
