Book excerpt: Avant d'être une science, la gemmologie est un défi que relèvent bon nombre de professionnels confrontés à ce que le profane appelle pierres précieuses et que la loi préconise désormais d'appeler pierres gemmes. Ce défi est simple, lapidaire pourrait-on dire: il est de reconnaître ces pierres, leurs variétés, leurs traitements, leurs synthèses et leurs imitations. Avant de faire appel au laboratoire, le gemmologue, le négociant, le joaillier, le collectionneur ou l'amateur doit être capable de reconnaître ces pierres en utilisant des instruments de base légers et facilement transportables. Les fiches de ce livre – plus de 150 – suivent la démarche analytique élaborée au sein de l'Institut national de gemmologie (ING) durant cinquante années d'enseignement et d'expériences: observation à l'oeil, au polariscope, au réfractomètre et autres outils spécialisés, mesures... Cassure, clivage et parting; résistance aux chocs, aux produits chimiques et à la chaleur; tests destinés à éviter d'éventuelles confusions... Ce guide de la gemmologie ne s'arrête pas à l'identification des pierres, et s'avère une mine d'informations pour parfaire sa culture: origine de la gemme, nature, classification, composition, système cristallin, formes avant façonnage, cause de la couleur, principaux pays producteurs et fabricants connus de pierres manufacturées... Clair et pédagogique, présenté dans une version bilingue français anglais, voici l'outil indispensable pour tous les passionnés, amateurs comme professionnels.
