Gem-A is the world’s longest established provider of gemmology courses. Our Gemmology Diploma evolved from the first gem course proposed for the UK Jewellery trade in 1908 and our prestigious Gemmology and Diamond Diplomas are recognised throughout the world.
In 1908, the National Association of Goldsmiths (NAG) established the NAG Education Committee to introduce gemmological qualifications for UK jewellers. This pivotal move was initiated by Samuel Barnett, a jeweller, and marked the inception of organised gemmology worldwide.
Then, in 1931, the Gemmological Association emerged as a distinct branch of NAG, fostering independence in education, research, and information provision. Interest in gemstones burgeoned over the following decades, prompting connections with global associations eager to teach the renowned Gemmology Diploma. Then, in the mid-90s, Gem-A evolved into a UK Education Charity.
Presently, Gem-A maintains Samuel Barnett’s legacy, providing world-renowned gemmology education while uniting a growing global network of gem enthusiasts and jewellery professionals.
