International School of Gemology Education

I stumbled upon the ISG when I felt defeated after knowing I couldn’t do the extremely expensive GIA courses. Through RJs courses you get book knowledge, but what I think is more important, you get his personal knowledge. Through him I figured out how to get my AJP through the GIA for free, and then received a scholarship to eventually pursue my GG through them. But the ISG is what is going to make me a gemologist, and a damn good appraiser.

I want to express my deepest gratitude to you for creating such interesting and full of knowledge course. ” Litigation and expert witness course” is a great addition to all my modest experience and will help me in future become more confident in litigation process. It was a great pleasure to be an ISG student and I hope to stay as active member ISG alumni community.

I appreciate you so much Robert. I too went to GIA and even took a few International Gem Society courses and I love the value placed on ethical selling that ISG places compared to every other course I’ve taken. I feel like being able to source ethically is hugely what was missing from my gemology training and credentials and I was able to supplement that with your program. Thank you for what you do for the field and community of gemologists everywhere.
