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.

Gemmological Instruments deals with the developments in diamond grading equipment and gem testing instruments since the publication of the first edition in 1978. These developments include improvements in the versatility and styling of existing instruments such as the reflectivity meter, the composite spectroscope, and the refractometer. It also addresses the criticisms in the first edition and provides a discussion of the advantages and disadvantages of different gem testing equipment. This book is organized into 16 chapters that describe groundbreaking instruments like the thermal conductivity diamond testers and home-constructed items that while innovative have not yet been commercialized. There are also chapters dealing with microphotography and identification of synthetics and stimulants. This book also provides a listing of gemstone constants and characteristic inclusions in natural and synthetic gemstones. This book will be of interest to people interested in equipment for gem testing and diamond grading.

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.

Since World War II the amount of information generated in the science of Gemology has increased tremendously. Therefore this book "Dictionary of Gems and Gemology" was written with the aim of providing a "relatively" complete dictionary to assist all students, hobbyists, scientists and interested parties in the fields of Gems and Gemology. The forerunner to this book was called "Dictionary of Gems and Gemology" (English-Persian, Persian-English, published in Tehran Iran in 1997). It was written with the aid of more than thirty refer ence books relating to gemology. In response to the effort required to clarify the terms within, I decided to compile a book that brings all the relevant terms into one book. This new book eliminates the use of different reference books and compiles nearly all the relevant terms into a one-stop useful text. It took twenty five years to collect the terms and the information so as to present a complete and functional lexicon. The text is supported by nearly 170 illustrations and 21 tables to provide detailed and succinct information. I hope and trust that this book will reach the high standard of other gemological dictionaries. If you have criticisms or suggestions, please feel free to contact me. Professor Dr. Mohsen Manutchehr-Danai Los Angeles, Tehran, Regensburg Acknowledgments The author acknowledges all those who were of valuable assistance during the writ ing and publishing of this book.
