5.00I love gemstones and jewelry, so I jumped at the chance to take an all day class in gemology and I am so glad I did. I thought I knew a fair amount about gemstones, but I found out that my base knowledge is just the tip of the iceberg. The class started with an overview of the different types of gems and their cystaline structure, which became very important the second half of the day. I was able to ask any question I had and received an answer. The information I learned will be invaluable in the future and I look forward to taking another class in the States to learn more. If you are ever planning on buying jewelry anywhere, you should take this class!
Good experience full of knowledge.

5.00This was an intense full day of geological information. Phillipe and his staff provided an extremely informative day of information concerning gems. Many myths were debunked and a ton of information was provided. From sources of semi precious and precious gem stones to the use of loop, microscope, and specific gravity measurement equipment to evaluated gems, Learn how to spot simulated gems and various treatment methods. If you are the least bit interested in gemstones, then this is a must do class. Well done!

5.00A fantastic day with Philippe who introduced us brilliantly to the art or profession (or both!) of gemology. He knew not only to share his passion for stones but also for Cambodia. We recommend without hesitation! Christophe and Elena H. from Paris
