Recognize the Gemstones (4h) - Discounted Rate

Recognize the gemstones Discounted Rate

Familiarise yourself with gemology and how to identify gemstones.

Transported into the ambiance of the great precious stone markets--Chanthaburi in Thailand, Ratnapura in Sri Lanka or Bogota in Colombia--you will learn to distinguish a group of different gemstones, which can seem very similar to the uninitiated.  You will observe stones with your naked eye and then with the professionals' instruments: hydrostatic scale, refractometer, polariscope, and specific gemologists' scale. 

About the course

If you are a student* or a job seeker*, you can enjoy the discounted rate of €15 for all courses and talks organized by L’ÉCOLE, School of Jewelry Arts in Lyon (25/11 – 3/12/2023), subject to seat availability.

*A valid student card or proof of entitlement must be presented.

Like a specialist, become comfortable with the gemologists' tools and train your eye in order to become a connoisseur.
