Download or read book Gemmology written by P. G. Read and published by Elsevier. This book was released on 2013-10-22 with total page 375 pages. Available in PDF, EPUB and Kindle. 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 Synopsis Beginner's Guide to Gemmology by : Peter G Read
Download or read book Beginner's Guide to Gemmology written by Peter G Read and published by Elsevier. This book was released on 2013-10-22 with total page 241 pages. 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.

Book Synopsis Gemmological Instruments by : Peter G Read
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 Synopsis Artificial Gemstones by : Michael O'Donoghue
Download or read book Artificial Gemstones written by Michael O'Donoghue and published by Robert Hale. This book was released on 2007-11-30 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title is now in paperback for the first time.Artificial gemstones have been well established in the trade for some time, but now, following further refinements in their manufacture, gemmologists worldwide are facing increasing problems with identification.Today, gem-quality synthetic diamonds, once deemed impossible to produce, are becoming widely available, and, moreover, it is possible to create almost any major gemstone in whatever colour is desired. Then, too, the growth of diamonds by chemical vapour deposition is destined to present further problems. The synthetic products of the past, particularly of the 1960s, are still available, and are puzzling the newer generations of gemmologists who have not encountered them previously.In "Artificial Gemstones", Michael O'Donoghue provides the definitive guide to the various manmade substitutes thus enabling anyone handling gems to identify them accurately. Starting with the theory of synthetic gem manufacture and an explanation of the production methods used for growing and/or improving crystals - with their ornamental application - the book moves on to list and identify the materials themselves. Some of these have natural counterparts; others are new minerals and do not occur in nature. The author lists the identifying internal and external features and tests, and the book contains colour illustrations to display the inclusions found in transparent materials. The book is completed by an extensive bibliography and a useful appendix of trade names.Gemmologists, gem dealers, lapidaries, curators, amateurs and students of gemmology and mineralogy will all find this an indispensable addition to their bookshelves.
