Our students and graduates say it best...
  • Thanks for all the wonderful lessons from ISG! I really enjoyed being a part of your Registered Gemologist Program. I have just passed my Registered Gemologist's Exam and can't wait to display my diploma in my jewelry store! I'll be happy to refer anyone to your program. As a former GIA student, I truly feel that your program offers the best hands on, practical, day to day knowledge that is available including GIA. Good luck in the new office and continued success! Sincerely, –Bill Warren, Pres. North Carolina Jewelers Association

  • 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
