The Gemmological Association of Great Britain (Gem-A)

I have been in the jewellery trade for 20 years, but my quest for knowledge never ceases. I decided to undertake the Diamond Diploma (DGA) in 2020. A really interesting course, which covered every aspect of Diamond, and a really excellent practical Diamond Grading Week and exam. I am now delighted to have achieved my qualification and will proudly place the much coveted postnominals DGA after my name. Update 2022: I am very pleased to say I have now achieved my Gemmology Diploma, and will proudly show FGA- Fellow of the Gemmological Association after my name.

Due to Covid I had to delay my exams several times, the staff both on-site and online has always been extremely helpful and friendly providing me with the necessary solutions. I did my FGA and Im currently doing the DGA online with Valentina, who has been a fantastic tutor, always ready to help and to answer any doubts I may have. The lab classes in the London headquarters, despite brief, are extremely useful to get hands-on knowledge, additionally tutors Matthew, Charlie and Craig were very knowledgeable and always ready to help.

It is always great to see Gem A stand at all major jewellery events. The staff are always frinedly and extremly helpful. I have been using a lot of their equipment for years and they are still in great condition, which is the testimony to the quality. I did my FGA and DGA with Gem A and found the courses indepth and interesting.
