Due to the ongoing situation with COVID-19, Gem-A London office is currently closed.
Our staff continue to work remotely and are not able to take calls, but we are responding to all enquiries via email.


At the heart of our association are our members and we host a number of events both in London, within the UK and around the globe where members can connect with Gem-A staff, fellow gem enthusiasts and professionals from within the trade.

GEM Central

Gem Central is an informative gemmology evening for Gem-A members, students and guests.

Depending on the topic, the session may take the form of theory-based learning with industry examples. It may be a more practical session where students can gain additional practical experience, gem and mineral enthusiasts can handle other collections and members of the jewellery trade can examine some of the new synthetic or treated stones on the market.

Regardless of the type of evening, Gem Central is always an excellent opportunity to learn information, to share knowledge and connect with others in the gem and diamond community.

Meetings are held once a month at Gem-A Headquarters in London and run from 6pm until 7:30pm. 

Trade Shows

Throughout the year we attend key trade events in locations around the world. As a global British brand it is important for us to meet with our international network of members, students, teaching centres and partners whilst showcasing our world renowned courses and instruments.
