The GIA (Gemological Institute of America) is a non-profit public benefit organization headquartered in Carlsbad, CA. Established in 1931, the institution consists of two fundamental parts: diamond education and a gemological laboratory. GIA created the “Four C’s” of diamond grading as well as the international diamond grading system.
The GIA’s Chairman, Ralph Destino, along with its Technical Director, John King, give guidance on how to purchase a loose diamond. They advise consumers to choose a reputable jeweler, then to become educated about how to recognize quality in a diamond, and finally, to purchase a certified diamond that blends quality and value.
Brilliance offers detailed diamond education, as well as a large assortments of loose diamonds. We are member of the Jewelers’ Board of Trade as well as the Better Business Bureau.
