Among rock-forming minerals, the colorful tourmaline group is a favorite of both mineral collectors and gemologists. Superb examples are found at many locales worldwide, and in diverse geological settings from pegmatites to schists. Over 120 clear, crisp photos show each mineral in its geological context. This book will help mineral and gem collectors understand tourmaline mineralogy and see how changes in nomenclature reflect our evolving understanding of the group. The text explains the chemistry and taxonomy of the group, the environment in which tourmalines form, provides a detailed entry for each mineral including locality information and full-color photos wherever possible so that collectors can see what good specimens look like and which minerals one might expect to find in association with them. An extensive bibliography is provided for readers who wish to learn more. Every serious mineralogist, gemologist, and rock hound will need this book.

This book provides a lucid introduction to the basics of gemmology. It familiarizes archaeologists, art historians and conservators with the science of gemstones and allows them to understand the basic concepts of their provenance, typology and treatments. Which are the main types of gems? What treatments can be applied? How does one analyse gems? How can gems contribute to archaeometrical research? This volume is written by four experts in the fields of gemmology and archaeometry and addresses both students who need an introduction to this field and professionals who want to refresh their knowledge of the topic. This work is part of a series of introductory texts that deal with a broad range of materials-related topics in archaeometry.
