“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
“It’s like a good who-done-it mystery. It just can’t be “put down.”
“This [material] 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.”
“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.”
