Gem-A, The Gemmological Association of Great Britain, 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, taught in five languages and in 18 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. Members receive our two internationally distributed publications, Gems&Jewellery and The Journal of Gemmology. Our on-site shop, Gem-A Instruments, provides quality gemmological equipment for students and the trade.
