Established by Robert M. Shipley in 1931, GIA was initially an institute for correspondence courses in Gemology studies but has since then become one of the world’s leading gemological institute for gemstone and jewelry grading, assessing, as well as reporting.

In 1934, Mr. Shipley published his first report of Gems and Gemology and in the same year, Gemology was recognized as legitimate science. Since then, GIA researchers have made many innovative additions to the knowledge of gemstones and jewelry.
