The Swiss Gemmological Institute SSEF is part of a non-profit Swiss foundation whose aim it is to further the science of gemstone testing and gemmological training.
The SSEF tests many of the world's most famous and exceptional gemstones. In an effort to share our knowledge and passion for gems we have developed these free online gem courses.
These are available in English, French, simplified Chinese, traditional Chinese, Japanese and Burmese. Currently the gems covered are Diamonds, Emeralds, Pearls, Rubies, Sapphires, Garnets, Jade, Opals, Spinels and Tourmalines,. More gems and more languages are in preparation. Stay tuned to updates by subscribing to our newsletter.
If you want to learn more about gems and how to identify, study, and grade them you can attend one of our in-person training courses in Basel, Switzerland.
