GIA (Gemological Institute of America) is a nonprofit organization based in Carlsbad, California, with a long history in gemology. It advances understanding of gemstones through research, education, and the application of scientific methods, revealing the origins and value of stones. The organization does not buy, sell, or appraise gems; instead it provides reports, education, and insights to help professionals and consumers make informed decisions with confidence.

Its work has helped establish widely used standards, including the 4Cs framework for diamond quality, and it has developed tools used across the industry. Founded nearly a century ago, GIA positions itself within the nonprofit sector of the gem and jewelry field and serves a global community. In early 2026, the organization announced expansion initiatives, including the opening of a new location and gemology school in Taiwan, signaling ongoing international growth.
