Download or read book Gemmological Instruments written by Peter G Read and published by Elsevier. This book was released on 2013-09-24 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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 excerpt: Enter into the fascinating world of precious gems through this unique volume that brings together the wonders of mineralogy and masterpieces of jewelry. Both a reference book and an exhibition catalog, Gems unveils the fascinating world of minerals and gems through a dialogue between the prestigious collections of the Muséum national d'histoire naturelle in Paris and the great French jeweler Van Cleef & Arpels. The Muséum national d'histoire naturelle in Paris welcomes the exhibition Gems from September 16, 2020‒May 4, 2021. This beautifully illustrated volume brings together an international team of mineralogists, scientists, and specialists in natural history and in the history of jewelry, under the editorial direction of François Farges, to explore the diversity of the mineral universe through an exceptional selection of geological specimens (some published here for the first time), legendary gems, and exceptional ornaments created throughout history. Raw crystals, cut stones, and jewelry are compared and contrasted, shedding light on both the natural wonders made by the Earth itself and the virtuoso creations of human hands that transform them into works of art.

Available in PDF, EPUB and Kindle. Book excerpt: What is a cabochon? What are the various types of gilding? What is vermeil? This accessible book—the first of its kind—offers concise explanations of key jewelry terms. The fascination with personal adornment is universal. It is a preoccupation that is primal, instinctive, and uniquely human. Jewelry encompasses a seemingly endless number of ornaments produced across time and in all cultures.

In any given society, master artisans have devoted their time, energy, and talent to the fine art of jewelry making, creating some of the most spectacular objects known to humankind. This volume, geared toward jewelry makers, scholars, scientists, students, and fashionistas alike, begins with a lively introduction that offers a cultural history of jewelry and its production. The main text provides information on the most common, iconic, and culturally significant forms of jewelry and also covers materials, techniques, and manufacturing processes. Containing more than eighty color illustrations, this guide will be invaluable to all those wishing to increase their understanding and enjoyment of the art of jewelry.

Download or read book Gemstones written by Michael O'Donoghue and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gemstones is the first attempt in English to bring together the geological, mineralogical and gemmological developments that have taken place during the last thirty years. Though there have been many gemstone books published in that time, most have been concerned, understandably and rightly, with the science of gem testing and have covered that area very well. Details of the geological occurrence of many of the classic gemstones, and of nearly all those which have only recently been discovered, have been less adequately dealt with. Coverage has been restricted to a number of papers in a wide variety of geological and mineralogical journals. Gemstones hopes to get the balance right. In the preparation of the book all the journals and monographs in the field have been consulted so that the book should stand for some years as the authority to which gemmologists and others turn in the first instance. Ease of reference and depth of coverage make Gemstones both a reference book and a bench book. Acknow ledgements I am grateful to Brian Jackson of the Department of Geology, Royal Museums of Scotland who read the manuscript and painstakingly indicated places where amendment or alteration was needed. I am also grateful to the publishers of the books on which the line illustrations are based. The colour plates present in the book derive from a number of sources, which I would like to acknowledge as follows. Plates 1, 4-15 and 17 Crown copyright reserved.

Available in PDF, EPUB and Kindle. Book excerpt: Beginner's Guide to Gemmology presents the profiles of the principal gem materials. This book discusses the interesting characteristics of gemstones as the growing consumer market jewelry resulted in increased sales of gem testing instruments. Organized into 12 chapters, this book begins with an overview of the development of the science of gemmology. This text then explains the fundamental qualities necessary in a gem, including color, hardness, specific gravity, crystallography, refractive index, pleochroism, critical angle, luminescence, and absorption spectra. Other chapters consider the organic gem materials, including amber, ivory, coral, tortoiseshell, jet, ebony, and pearl. This book discusses as well the various methods used in the production of man-made gemstones and the commercial use in gem testing. The final chapter deals with the composition of synthetic gemstones. This book is a valuable resource for gemmologists and jewelers. Students who intend to become a qualified gemologist will also find this book extremely useful.
