Marsha Ignatovich

"It was my dream to study gemology in Israel. I know that Israel is the best in diamonds. So, my dream came true. I studied gemology in the Center of Gemological Studies C.G.S with Hadas Dori Bar Moshe. It was individual course in English, and I would like to say, that it was wonderful education! Very professional course, good gemological equipment. I had a lot of practice hours, during it I saw many diamonds in microscope and in loupe. I received full knowledge about diamonds grading. Education process was very comfortable and friendly. Hadas is a very professional teacher, always ready to help, answer any question. I met not only a very professional specialist, but my friend now! I studied with a great pleasure. I highly recommend C.G.S for studying gemology."

Katherine Gorman

"The C.G.S. course founded by Eli Dori in 1979 and taught by his niece Hadas Dori-bar Moshe is one of the best courses I have come across. The classes vary in size but what is constant is the professional, caring and fun atmosphere in which one is engaged.
From the first moment one walks into the class to the day one leaves proudly holding a Diamond Grader Certificate is an absolute pleasure.
Every aspect of the course is explained clearly and thoroughly and each lesson devotes time to a lecture and practical application so that in a few short lessons you have the confidence to Diamond Grade and fill out a certificate with accuracy.
If you are serious about a position in this industry or simply want to refresh ones skills, then there is no better place to be than with the C.G.S family.
I will forever be an ambassador for them."

Maxwell Oguntuyi

"I am using this medium to say a big thank you to Hadas and Eli Dori. Its been an awesome time studying Gemology and the beautiful art of Diamond Grading in your highly esteemed citadel of Learning (C.G.S).
It\'s a period well spent, you guys are the best at teaching everything about Gemology and most especially Diamond Grading.
I also want to thank my classmates Katherine Gorman and Amit Lipszyc, you guys rock.
No teacher/student barrier, rather we had a synergy of a micro-community, to learn, speak and be listened to and share our experiences, which made us to excel in our training as Diamond Graders.
Lectures are delivered in both English and Hebrew languages simultaneously, a Unique selling point for C.G.S.
I highly recommend C.G.S, and I grade them Excellent because they represent the optimal 4C\'s of a Diamond."

"I would definitely recommend this course to anyone working with diamonds, whether they are total novices like me, or people who already work in the industry and want to polish their skills and knowledge. The course is well structured and comprehensive. And, although the course is fast-paced, it is fun and easy to understand. The teachers are very supportive and they adapt to individual student's needs. All the students in my class had a great time!".
