Frequently Asked Questions
Why does a diamond have to be loose for the Diamond Grading Report and Colored Diamond Grading Report?

We grade only loose diamonds because a mounting or setting can obscure or influence the color, cut, and clarity grade and make it difficult to determine an exact carat weight. Grading loose stones also allows GIA to detect any treatments applied to the diamond without damaging the stone or the mount.
