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.
