After a historical introduction and a few technical notions, a master enameler will help you grind the raw material and choose the powders that provide the colour. In creating the decoration of your jewellery, you will learn the secrets of metal engraving, as well as the techniques of "champlevé" and "plique à jour."

Transported into the ambience of the superb precious stone markets--Chanthaburi in Thailand, Ratnapura in Sri Lanka, or Bogota in Colombia--you will learn to distinguish a different group of 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.

Whether you are attracted to precious stones, interested in the history of jewellery - from prehistoric times to the present day - or its many artistic speciality professions, these two-and-a-half hours classes will lead you onto the path of knowledge.
