The GIA grades diamonds on a scale of D (colorless) through Z (light color). All D-Z diamonds are considered white, even though they contain varying degrees of color. True fancy colored diamonds such as yellows, pinks, and blues, are graded on a separate color scale.

In order to determine how much your diamonds are worth, you need to have them evaluated. But, it’s important to go to someone that is fully knowledgeable on the subject who can give you an accurate appraisal according to your diamond’s GIA grading report.
