About this Association

Gem-A, the Gemmological Association of Great Britain, is the world’s longest-running international provider of gem and jewellery education. A UK charity, they can trace their lineage back to 1908 - that’s over 112 years of experience and expertise in the field of gemstones and minerals. It is their mission to advance the understanding of gemstones through education, membership, engaging international events and a community-driven approach to accuracy and best practice.

Gem-A HQ is based in the heart of London’s diamond district and enjoys a well-established connection to the rest of the world through a network of Accredited Teaching Centres (ATCs). Studying with Gem-A gives student’s confidence to pursue their ambitions, knowing they are supported by a solid foundation of gemmological knowledge that goes beyond aesthetics and delves into the fascinating science of gems.

On successful completion of their Gemmology and/or Diamond Diplomas, graduates can apply to become a Fellow or Diamond Member of Gem-A, and use the prestigious post-nominal letters FGA and/or DGA after their name. Only Diploma holders of Gem-A’s Gemmology and Diamond qualifications, and those who remain paid-up Members of the Association, are entitled to use these letters.

By remaining Members of the Association, Graduates have shown their commitment to continued professional development and agree to adhere to the Gem-A by-laws and code of practice. You can view a full list of FGA and DGA Members by clicking the ‘ FGA & DGA Register’ button at the top of this page.
