"The Diamond Specialist Course is excellent, as comprehensive as it could be, and its structure offers all the theoretical and practical knowledge for grading and evaluating diamonds."

"I very much liked the Diamond Specialist Course, it is excellent, as comprehensive as it could be, and its structure offers all the theoretical and practical knowledge for grading and evaluating diamonds. Moreover, IGS related articles complement and consolidate what you learned during the course. It is true that the previous graduation of the Professional Gemologist Course has made it easy for me to understand and learn the lessons from this course, which has really become a specialization in the field of diamonds. I would recommend anyone to take the Professional Gemologist Course first and then the Diamond Specialist course."
Daniel Penescu

"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."

"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."
