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.

This edition has been revised and expanded to reflect recent and varied developments in the highly specialized field of gemology. Among these are: gemstone synthesis; imitation gems; the alteration of gems to improve, add, remove or otherwise change their color, phenomena or clarity; the importance and widespread uses of the microscope to reflect the aforementioned developments; and a number of new gem minerals or new forms of previously described minerals recently discovered or actively marketed for the first time. The chapter on Descriptive Gemology has been divided into two groups: important gemstones (those gem materials most widely used in jewelry and ornamental objects) and less important gemstones (those less commonly encountered).

As entertaining as it is incisive, Stoned is a raucous journey through the history of human desire for what is rare, and therefore precious. What makes a stone a jewel? What makes a jewel priceless? And why do we covet beautiful things? In this brilliant account of how eight jewels shaped the course of history, jeweler and scientist Aja Raden tells an original and often startling story about our unshakeable addiction to beauty and the darker side of human desire. What moves the world is what moves each of us: desire. Jewelry—which has long served as a stand-in for wealth and power, glamor and success—has birthed cultural movements, launched political dynasties, and started wars. Masterfully weaving together pop science and history, Stoned breaks history into three categories—Want, Take, and Have—and explains what the diamond on your finger has to do with the GI Bill, why green-tinted jewelry has been exalted by so many cultures, why the glass beads that bought Manhattan for the Dutch were initially considered a fair trade, and how the French Revolution started over a coveted necklace. Studded with lively personalities and fascinating details, Stoned tells the remarkable story of our abiding desire for the rare and extraordinary.
