Institut National de Gemmologie

Since 1967, Institut National de Gemmologie has trained gemmology and high jewellery professionals. 

At l’ING, we have studied gems and precious stones since 1962, training professionals for tomorrow’s world.

Gemmology is a fascinating sector for those who are passionate about gems and precious stones. Our school’s history began with the creation of the Association Française de Gemmologie by researchers, professionals and enthusiasts focused on studying stones. A few years later, in 1967, Institut National de Gemmologie (ING) was founded.

The School has two campuses in France: Paris and Lyon. It trains more than 200 students each year.
