It's great to see good appraisal methodology being taught. In the UK we have specific courses that we have to complete before we can become registered valuers (appraisers) but it doesn't seem the case worldwide.

The ISG courses are the best and at your convenience. I completed the RGA program by taking one course at the time. It took me some time, but I was able to make a living and to study without a time pressure. Thank you Robert! Marina W.
I worked on my GG several years after completing my RGA. I was able to complete GIA Diamonds & Diamond Grading as well as Colored Stones courses in a week each based on what I learned at the ISG. Great education and support throughout the years. Matt U.
I am a G.G. and F.G.G. I signed up for the I.S.G. in its infancy as a kind of a refresher because so many things had changed in the field of gemology since I got my degrees in the mid 80's. I was impressed with the quality and quantity of information available through the courses. Robert James, a graduate of both the Gemological Institute and British Gemmological Association, is constantly updating the material and refining the presentation. I would recommend the ISG for those who want a user friendly and reasonably priced study of gemology. –Barbra Voltaire FGG, GG Gemology Online
I received the material to begin the program as a ISG Registered Gemologist Appraiser yesterday. I am thoroughly impressed with your program. The material was received in unprecedented time between payment and delivery of material. I have only read the first 4 chapters of The Pearls Course and have learned more than I have acquired in a lifetime of gemstone study and research. The study material and recommendations for learning are not only helpful, but it would seem that anyone taking your courses are sure to be successful. I look forward to this study in your program with confidence and without apprehension. I am delighted to be one of your new students. Thank you for making this learning process possible and accessible.–Adele S. ISG Student
