My experience with Gem-A Instruments has been excellent every single time. I’ve dealt with them on numerous occasions during the last couple of years both for me personally as also on behalf of A.E. Ward & Son. They have a large range of gemmological instruments, books and gadgets available. Instruments such as the refractometer and microscope which A.E. Ward bought from Gem-A years ago are absolutely invaluable and used daily. Sam is incredibly helpful and clearly very knowledgeable about everything stocked. She is always willing to explain something or give advice on any of the instruments and orders are prepared promptly. I highly recommend Gem-A Instruments!Posted onTrustindex verifies that the original source of the review is Google. It is always great to see Gem A stand at all major jewellery events.

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. One additional word of thanks goes to my tutor Valentina Molon, she was very very knowledgeable and offered superb guidance throughout the course.
