gemmologue.ch is an independent project devoted to gemology, to the materials it studies and to the relationships people have built with them over time.
The site publishes a growing collection of encyclopedic books, Le monde des gemmes (The world of gems), written by Ramon Cortes, Graduate Gemologist (GIA), and offered freely, with no advertising:
- The Meteorite: a complete introduction to meteoritics · presentation in English → · read in French →
- The Diamond: from the heart of the Earth to the center of power, in six books · presentation in English → · read in French →
- The Pearl: the only major gem born of a living creature, with a photographic gallery · presentation in English → · read in French →
- Colored gemstones: in preparation
A weekly series of short articles (Actualités) accompanies the books, along with photographic galleries and a field notebook (Carnet du Gemmologue).
A note for English-speaking readers. The books are written in French. Modern browsers translate the pages on the fly, and the figures, tables and structure remain fully usable in translation. Each book has an English presentation page with an accurate, human-checked translation of its full table of contents.
