Recognize the Gemstones (4 hrs)

Transported into the great precious stone markets — Chanthaburi in Thailand, Ratnapura in Sri Lanka or Bogota in Colombia— discover how to distinguish a group of different gemstones, guided by two gemologists.

Divided into teams, conduct the investigation around a colored stone of your choice. First, learn to observe stones with your naked eye, and then to handle the gemologists' identification instruments (refractometer, spectroscope, dichroscope...), to refine your investigation.

Finally, by the end of the course, you are able to identify the stone you have selected.
