About the ISG

About the International School of Gemology

The International School of Gemology was founded in 2004 by Robert James, FGA, GG, after serving as an Allied Teaching Center of the Gemmological Association of Great Britain since June of 2000. Mr. James was a tutor for the Gem-A FGA program, serving as educator for the world’s oldest and more respected gemology education organization. From 2014 – 2019 the ISG became a 501(c)3 Non-Profit Education Organization under the name of the Insurance Institute of Jewelry Appraisal. However, in late 2019 it was decided to return to our roots as a gemology based education organization with the ability to provide quality education around the world, and not just centered in the United States. As a result the ISG was relaunched under its original structure in December, 2019. 

As your lead instructor, Robert James FGA, GG, also holds the world’s highest credentials in the field of gemology. He is a Fellow of the Gemmological Association of Great Britain (see FGA Diploma at left).
