What people are saying
" I have never known or heard of an organization that offers so much for its members, and at such a low cost. What started as a hobby in 1998 and now is a small home business for my wife and I has been made so much easier by the information you supply. Thank you. "Ernest and Peggy Roisch, Rainbow Rocks, LTD IGS Member
" You know the best thing that I have learnt from your great courses is that it does not matter how much you think you know about gems, you never stop learning, each day there is something more learn, it will never stop. Thank all for the help, education and support that you give IGS members. "Peter CheckleyIGS Member
" I have been on the distant sidelines of the jewelry business for a long time with a great love of colored stones and working with gold. I must tell you that IGS is a Godsend for me, as I do not have the resources or the six months required to get a GG from the GIA now. "Charlie BernheiserIGS Member
