Gemological Institute of America (GIA)

Founded in 1931, the Gemological Institute of America, or GIA, is an independent, non-profit organization considered by many to be the world's foremost authority in gemology. Introduced in 1953, their diamond and gemstone grading system is recognized worldwide. Manufacturers from around the world send diamonds and gems to GIA for examination and analysis.

The GIA's mission is to increase consumers' trust in diamonds and jewelry by upholding the highest standards of integrity, academics, science, and professionalism. They work toward this goal by providing jeweler and consumer education, conducting meticulous research, and developing state-of-the-art laboratory instruments for diamond inspections.

When a diamond is accompanied by a GIA certificate, the consumer is assured that the stone has been analyzed by an unbiased gemologist who upholds the highest standards of integrity, science, and professionalism.
