Established in 1931, the Gemological Institute of America (GIA) is the world’s foremost authority on diamonds, colored stones, and pearls. A public benefit, nonprofit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry.
As a charismatic businessman originally from Los Angeles, CA, he positioned himself as a jewelry expert, but it was his lack of expertise that started him on the path that led to the founding of GIA—the Gemological Institute of America.
The course and guild evolved into GIA, with the institute publishing books and setting up its first lab in 1931. Today, GIA is a leader in gem education, research, grading and instrumentation and operates globally, with facilities in eleven countries and across four continents.
