Abstract
Gemology: the thousand colors science. The Gemology is the science that studies the gemological materials, which vary between emerald, amethyst, tourmaline, topaz, diamond, among many others. Brazil produces a large part of these varieties and, paradoxically, the Brazilian scientific gemology is still immature. Currently, new technologies improved production and gems treatment techniques of most of these minerals and, consequently, these new substances flooded the market. Alarming events related to technical miss concepts and trading motivated the author to produce this publication in order to disseminate basic concepts about Gemology. The lack of knowledge on the part of the professionals and gemology lovers can lead to disappointments and even financial losses for both parties. The objective is to educate and teach this science in a conscientious way, through simple experience and knowledge, which may provide greater autonomy for all audiences and present, to those tireless admirers of beautiful things, the enchanting universe of a thousand colors.
