Gem-A Level 6 Diploma in Gemmology

Gemmology Diploma

Our Gemmology Diploma is the most prestigious international gemmological qualification in the gem and jewellery trade. You will look at a wider range of gems, synthetics and treatments, and will build upon the practical and theoretical knowledge learnt during your Gemmology Foundation course, leading to a more in-depth understanding of gemmology and the principles of gem testing and enhanced gem identification skills. Upon completion of the Diploma course you will be confident at handling, testing and identifying a wide variety of gemstones.

Graduates of the Gemmology Diploma course can apply for Fellowship of Gem-A, allowing them to use the letters FGA after their name. FGA status conveys a student’s knowledge, integrity, membership of a professional body and commitment to professional development, and is highly recognized within the trade. Your name will appear on the FGA and DGA register, available to the public to view on our website, so anyone can see that you are qualified and a registered Member with us — ensuring their peace of mind whilst advertising your knowledge and integrity.
