All colored diamonds, including pink diamonds, are evaluated based on three elements:
The GIA (Gemological Institute of America) has a color grading system used to evaluate the quality of colored diamonds, including pink diamonds. The GIA scale ranges from Faint to Fancy Vivid and represents the intensity of the diamond's hue. The higher the grade, the more intense and vivid the hue. In the GIA scale, diamonds are ranked in order of importance. Color D is considered a perfectly white diamond. The scale then descends to light pink, which is the lightest shade of pink, and to vivid pink, which is the most intense.
