"Ho frequentato il corso di Hadas in Ramat Gan e mi sono trovato benissimo! Hadas è una bravissima insegnante nonché persona! Il corso viene svolto in parte in ebraico e in parte in lingua Inglese ed è molto facile da comprendere! Do un voto di 10/10! Tutto è andato benissimo, sia al livello tecnico che al livello umano! Consiglio vivamente chi volesse frequentare il corso di Hadas dall’Italia in quanto mi sono trovato veramente bene! Leggevo solo recensioni positive e ho toccato con mano quanto letto! Grazie di tutto Hadas!"

"I just completed my studies and it was the most amazing experience. Hadas has such a gift of presence in class. She kept all of us so motivated and was there for us every step of the way making sure we understood the lessons. The material we covered in class was quite thorough. I loved working with the diamonds and getting better and better at inspections as I became more educated. Coming to class was something I looked forward to because Hadas kept the pace moving and you feel like you’re part of a small family. Everyone in my class enjoyed each other’s company and there were plenty of laughs. I already miss everyone but will remember the experience fondly. I recommend this course to anyone who wants to learn the diamond business. Bravo, Hadas! You are one hell of a teacher! I’ll miss you. The Texas Lady."

Hadas is a wonderful, warm-hearted, compassionate, kind, loving, caring, patient and FUN teacher... not only a teacher, she is my good friend and am proud to say it. The way she teaches, you cannot feel lost, she’s focused on every student she teaches. I have learnt a lot from her, more than that I cannot say, she has SUPER experience. My 6 weeks class went by so fast, why? Because, I had so much fun laughing and learning. Trust me, you have nothing to lose, take her class and see for yourself what a SWEETHEART she is.

Alisa Botebol

Bonjour, je m\'appelle Alisa."
Je viens de terminer la formation de juin avec Hadas. Cela a été une formidable expérience, autant techniquement, que humainement.
Hadass est une extraordinaire professeur passionnée par son métier. Elle m\'a tout enseigné en anglais alors, qu\'elle enseignait simultanément aux autres élèves en hébreu.
J\'ai adoré venir chaque matin apprendre la partie théorique et pratique de l\'étude du diamant dans une atmosphère très agréable.
Je vous recommande vivement ce cours."

Alisa Botebol

Hello, my name is Alisa."
I took the group course with Hadas .
She taught me in English, it was great.
It was an amazing experience in an amazing atmosphere.
Hadas is a really good teacher: professional, passionate by her job she loves to give to her students, she is available for them, always smiling and super patient.
The studies were amazing; I loved to come every morning to learn the theoretical aspect and the practical aspect of diamonds. I could have not asked for more.
I highly recommend this course."

Ainara Larranaga

"This is the best course I could have ever taken. Hadas is professional, open, dedicated, fun and amazing! The class is not just about sitting around and getting board, listening to lectures or reading the book. It\'s all the contrary, it\'s about enjoying the lectures (because it\'s so interesting), enjoying practices and appreciate every single stone that you look through. It makes you concentrate and I could even add, relax. It makes you to want learn more and more. I enjoyed every single class and every moment. I could have not asked for more. And if you ever are interested in stones or want to discover a new world, I really highly recommend this course, because it prepares you for all what you need to know to be a gemologist."

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."

Gadi Panka

"Beyond the smile and the great personality, Hadas is a professional gemologist. She allows you to understand the material in the best way.

"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!".
