Book excerpt: Practical Gemmology has for decades been recognized as the standard work for those learning how to identify gems and ornamental minerals. It is recommended by educational authorities as a course textbook, and it is also particularly suitable as a self-instructor for those entering or hoping to advance in the jewellery and gem trades, or for the keen amateur. The 21 sections comprise notes on the formation of gem materials, and a section on luminescence and electrical effects bring a more modern approach to this part of the subject. More information is given on the inclusions seen in gemstones, and the newer synthetic stones are discussed. The methods used in cutting gemstones and details of more of the unusual gemstones now cut and polished are also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
