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

During this course 
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 professsionals' instruments: hydrostatic scale, refractometer, polariscope, and specific gemologists' scale.    

This course is taught by two gemologists.
