Book Description
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.

Book Description
Gemmology is a text for students preparing for the Gemmological Association's Preliminary and Diploma examinations. The book is more expansive and up-to-date than the author's earlier book, Beginner's Guide to Gemmology. The book deals with the practical and theoretical sides of gemmology. Tracing the background and science of gemmology, the book covers the gem material, geological formation, and occurrence of gemstones on the earth. The composition of gemstones from the atoms, elements, molecules, and compounds comprising them is analyzed, and the relationship between chemical composition and durability of the stone is explained. The basics of crystallography is mentioned as a tool toward understanding gemmology after which cleavage, parting, and fracture are done. A gemstone's durability and hardness and how the latter influences engineering tests and the mining techniques are compared. An important test technique to identify unmounted stones is the measure of specific gravity using displacement measurement methods and hydrostatic methods. After more descriptive details are given in identification of gemstones, whether these are synthetic or simulants, through a comprehensive explanation of the materials found in these other gemstones, the fashioning, through shaping or polishing, of gemstones is explained. Emphasis is given on the critical angle in which light rays pass in different rock densities, and then the cutting styles, gemstone polishing, and grading are discussed. Students studying for the Gemmological Association's Preliminary and Diploma examinations, jewelers, lapidarists, and diamond cutters, as well as those engaged in the hobby of gemmology, will find this book helpful and full of information toward their endeavors and hobbies.

Book Description
Most of the material presented here was originally published in Gems & Gemology as articles and lab notes (short reports from the GIA Laboratory, formerly called the Gem Trade Laboratory) or as Gem News/Gem News International items between the years 1938 and 2007. Also included are summaries of presentations at GIA's 2006 International Gemological Symposium and Gemological Research Conference, which originally appeared in the Fall 2006 Proceedings volume produced by Gems & Gemology staff. The present work is organized in two main parts on color treatments and clarity treatments, with color photos and microimages on almost every page. Chapters in the section on color treatments cover coated diamonds, irradiated diamonds, and annealed diamonds. Chapters in the section on clarity treatments cover laser-drilled and glass-filled diamonds. Material is presented in chronological order to help readers follow the evolving areas of interest and understanding of these treatments. Some of the older material includes editorial comments to explain now-unfamiliar concepts or discuss significant development since the original publication. The book includes a poster-sized color chart enclosed in a side pocket, with color photos demonstrating diagnostic features of filled diamonds and testing techniques. Shigley is a distinguished research fellow at the GIA Lab in Carlsbad, California.
