Gemology is a specific branch of Mineralogy dealing with the study of the gems. In particular it refines minerals which, because of some of their intrinsic qualities (rarity, colour, beauty, transparency,etc..) could be used as precious stones or as decorative materials at the jewelry store.

The Gemologist analysis severely keeps the stone undamaged and is able to certificate the authenticity of the gems. Besides that, it has the aim to inform the market about the existence of imitations in the stone business, synthetics gems done in the laboratory or specific treatments able to hide imperfections of the stone.
