Gem-A courses and qualifications are both high-level and officially accredited in the UK – Gem-A is an awarding body. This is one reason our qualifications are so highly regarded worldwide. All our courses emphasise the significant importance of rapid, self-reliant observational and practical ability, using a thorough knowledge and understanding of gemmological principles. Gem-A courses also foster the ability to choose appropriate testing methods based on intelligent observation for practical decision-making. The theory part of diploma courses helps you gain a deeper understanding of your decision-making processes in practical gemmology.
