What Students Say?

  • 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!

    Bill Warren, Pres. North Carolina Jewelers Association

  • I was just about to give up on my dream… I found The ISG. It´s just fantastic that I can be on my sofa in Stockholm and study gemology and not only keep a dream alive but also living it. Thank you for given me, through your enormous work & great experience and knowledge, this opportunity by establishing the ISG!

    Right now You are my hero!

    Daniel S., Sweden

  • I was impressed with the quality and quantity of information available through the courses.

    Barbra Voltaire FGG, GG, Gemology Online

  • I believe I that I have not thanked you for having this course. It was the best thing I have ever done. Your price is what people like me who did not know anything about gemology like to pay. And the course material is great just like the instructor.

    Mattias G., ISG Student in Sweden

  • Hi RJ,
    I am so thrilled and happy to have received my RGA from the ISG. I pray and only hope for the massive growth of your incredible organization. When I started GIA in 1978 the program was nothing in comparison to what you have offered. It is a shame that so many people are unaware of what wonderful things your program offers not just from the standpoint of earning a diploma; also from all of the information you’ve let us with which is an appreciated flood. I still look forward to one day meeting and or working with you in the future. I look forward to you starting an alumni Association as well.
    Warmest regards and thank you for everything,
    Craig Sperling
