What is Gem-A?

The Gemmological Association of Great Britain can trace its origins back to 1908. The world’s first qualifying gemmology course originated in London and the first gemmology diploma was awarded in 1913.


The first gemmology Correspondence Course followed in 1921. The Association became an independent organization in 1931 and combined with the Gem Testing Laboratory of Great Britain in 1990 to form ‘GAGTL’. These initials were replaced by the ‘Gem-A’ logo in 2001. The Gem-A headquarters is situated close to Hatton Garden in central London and contains the Education office, Gem Tutorial Centre, Membership office, Gem Testing Laboratory and Gem-A Instruments.
