Welcome to the ISG StudyGems Program where students in the United States can rent gemstone sets for gem identification testing and grading. Due to customs and shipping problems for other countries, we can only ship these sets on loan within the U.S. at this time. We are working on cost effective methods to bring this to our world-wide student body as soon as possible. ISG Students please read the StudyGems Loan Program Rules from the top menu to understand how the program works and your responsibilities.
