"It doesn't matter how much you think you know about gems, you never stop learning"

"You know the best thing that I've learned from your great course is that it doesn't matter how much you think you about gems, you never stop learning. Each day there is something more to learn, and it will never stop. Thank you for all the help, education and support that you give IGS members."
Peter Checkley IGS Pro Member

"It's like a good who-done-it mystery. It just can't be "put down."

"You are one heck-of-a-writer. This course is so well written, that I'm convinced that anyone, even me, can understand and master this material. After having read the first four introductory articles, I find myself actually wanting more time to study. It's like a good who-done-it mystery. It just can't be "put down."

"IGS is a Godsend for me"

"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 Bernheiser IGS Member
Becoming a Pro Member of IGS just made good sense for my business. The gemology resources are fantastic, and my profile lets potential customers know I am serious about colored gemstones. And frankly, if I get any exposure to potential customers it's a no-brainer.
Paul Bierker, Paul Michael Designs Jeweler, IGS Pro Member

"I owe my gemology knowledge to IGS."

"You are indeed a “Guru” in the true sense of the term. Your knack of simplifying the most complicated topics and your constant endeavor to update the existing information are really unique. I owe my gemology knowledge to IGS."
