s had made formal education essential. This committee matured into the Gemmological Association of Great Britain, a Branch of the NAG, and eventually became a wholly independent organisation. Now Gem-A is a registered UK charity and its gemmology and diamond courses are taught in some 25 countries worldwide.
Gem-A provides international recognised certificated courses in gemmology and diamond as well as offering a wide range of short courses, lab classes and one-day workshops, catering for both beginners and experts in the field.

Foundation in Gemmology course (leading to Cert. GA status)

Certificated courses can be studied in-house at the Gem-A London headquarters through daytime or evening classes, at one of Gem-A's international Accredited Teaching Centres or by Open Distance Learning (ODL) online classes.
Gem-A holds an annual conference, bringing together international speakers and delegates to meet and discuss important updates within the gem industry. It publishes the quarterly magazine Gems & Jewellery as well as the annual Journal of Gemmology.
