I loved this course! We were introduced to a wide breadth of gemstones, with the perfect balance of technical lectures as well as some hands on lab work. Every lecturer was a skilful teacher and their passion was absolutely infectious. The course materials were excellent too. Highly recommend!

I had begun to think there was little left in life to interest or inspire me, merely repeats of things done before, then I enrolled in the courses at GAA House. My only regret is that I did not know about gemmology studies thirty or forty years ago. This course has awoken forgotten areas from memory and subjects from school, along with a thirst for lost delights.
