Buying GIA Certified Loose Diamonds

You may already know to look for quality diamond jewelry, but how do certified GIA loose diamonds differentiate from standard stones? Any diamond that has an accompanying GIA certificate simply means that it has been authenticated, proven natural, and graded against the 4 big C’s of diamond quality. Color, Clarity, Cut, and Carat weight. These are the determining factors that gauge a loose diamond's quality and value. GIA classifications serve as the standard method of comparing and evaluating a diamond’s unique attributes.

Gray & Sons Jewelers will never sell a diamond without getting it professionally certified by the experts at the Gemological Institute of America (GIA).
