Conceived 73 years ago in the august tradition of Europe’s most venerated institutes, GIA discovers (through GIA Research), imparts (through GIA Education), and applies (through the GIA Gem Laboratory and GIA Gem Instruments) gemological knowledge to ensure the public trust in gems and jewelry.

With nearly 900 employees, the Institute’s scientists, diamond graders, and educators are regarded, collectively, as the world's foremost authority in gemology.
