GIA Certified Diamonds

The Gemological Institute of America (GIA), founded in Los Angeles in 1931, is an independent, non-profit organization considered by many to be the world's foremost authority in gemology. In 1953, the GIA created its International Diamond Grading System, which specifies uniform criteria for grading diamonds. The GIA grading system is recognized worldwide, and diamond manufacturers from around the globe send diamonds to the GIA laboratories for examination and grading. Even the White House has trusted the GIA for answers to diamond-related questions. A GIA Diamond Grading Report is the most widely understood and trusted set of credentials that can accompany a diamond.

The GIA cut grade of a diamond is determined on an assessment of seven factors. The first four-polish, symmetry, weight ratio, and durability-refer to the make of the diamond. The remaining three-brightness, scintillation, and fire-describe the appearance of each brilliant round-cut diamond. Note: The GIA grades brilliant round-cut diamonds on a five-step scale.

Brilliance Fun Fact: The Gemological Institute of America (GIA) has graded some of the world's most famous diamonds.

Choosing a GIA Certified Diamond

GIA Gem Trade Laboratory Reports are regarded throughout the gem and jewelry industry worldwide as the hallmark of integrity, reliability, and consistency in gemological services and research. This being said, a GIA certified diamond's quality is guaranteed, and is therefore more valuable than an uncertified diamond stone. GIA Certification allows non-experts to make educated diamond buying decisions. That confidence is what GIA diamond certification provides.
