Gem-A is the world's longest established provider of gem and jewellery education. Our prestigious Gemmology and Diamond Diplomas are globally recognised as qualifications of the highest status. Our Gemmology Diploma, now taught in five languages and in 17 countries around the world, is the direct descendant of the gem course that was proposed for the UK jewellery trade in 1908.

Today Gem-A forms an international community of gem professionals and enthusiasts. With our commitment to high educational standards, we serve the interests of the gem and jewellery industries and support gemmological research worldwide. In addition to our educational programmes  we also provide membership, including the world-famous FGA and DGA memberships, as well as events and an annual conference.

Members receive our two internationally distributed publications, Gems&Jewellery and The Journal of Gemmology.
