The Gemological Institute of America, or GIA, was established in 1931.  Its mission is to protect purchasers of gemstones by providing education, research and laboratory services to enable them to accurately establish the provenance and quality of gemstones and pearls.

GIA have education programmes running both on-line and on the campus in Great Russell Street in London.   They also have gem laboratories in the major gem cities of the world testing stones and suppling certificates that accurately measure, weigh and describe every feature of the stone in great detail.
