Insight into the Gemological Institute of America








Established in 1931, the Gemological Institute of America is the world’s foremost authority on diamonds, colored stones, and pearls. GIA is where students from all over the world learn the intricacies of the gem and jewelry field. The GIA exists to protect all purchasers of gemstones by educating Graduate Gemologists to provide their expertise needed to accurately and objectively determine gemstone quality.

Since the Gemological Institute of America was established 79 years ago, there have been only 200,000 graduates from 13 schools in 10 countries. The Graduate Gemologist (G.G.) diploma, which focuses on gem grading and identification, is the industry’s highest professional credential. Most notably, the GIA is the author of the 4Cs and the International Grading System-the worldwide standard for evaluating diamond quality.
