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.

Download or read book Gemstones and Their Origins written by P.C. Keller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each gem deposit-whether of primary origin in the parent rocks; or secondary as alluvial placers in valley floors, river gravels, or the sand of oceanic shelves presents an eloquent chronicle of the Earth's life story. It reveals to the expert the prodigious processes which formed the present crust of our planet, of which this volume discloses a small but exciting detail. The materials of the Earth's crust are the rocks. In this book, the author expounds on how they were formed, why they altered, why they became the cradles of precious gemstones, how they are categorized, and how they are now exploited by man. What initiates the growth of gemstones? How do they crystallize? Why do gemstones of the same species, originating from different sources, vary? What causes the occurrence of varieties? Why do diamonds, unlike other precious stones, occur not near the Earth's surface in its crust, but deep down beneath it in the upper mantle? These are only a few of the entrancing subjects discussed in this enlightening volume. The reader learns that the Earth is surprisingly alive and altering constantly-sometimes through slow and equable changes and at times by violent and tremendous cataclysms, events from which gemstones issue.

Available in PDF, EPUB and Kindle. Book excerpt: A sweeping history of our enduring passion for diamonds—and the exploitative industry that fuels it. Blood, Sweat and Earth is a hard-hitting historical exposé of the diamond industry, focusing on the exploitation of workers and the environment, the monopolization of uncut diamonds, and how little this has changed over time. It describes the use of forced labor and political oppression by Indian sultans, Portuguese colonizers in Brazil, and Western industrialists in many parts of Africa—as well as the hoarding of diamonds to maintain high prices, from the English East India Company to De Beers. While recent discoveries of diamond deposits in Siberia, Canada, and Australia have brought an end to monopolization, the book shows that advances in the production of synthetic diamonds have not yet been able to eradicate the exploitation caused by the world’s unquenchable thirst for sparkle.

Available in PDF, EPUB and Kindle. Book excerpt: It has been known throughout the ages that gemstones and crystals possess energies that can be used to aid in a wide range of activities. From healing to gathering knowledge, from mediation to protections, stones and crystals have long been useful tools in assisting practitioners of various spiritual arts in reaching their potential. In this informative, updated edition of a classic text, author and gemstone properties expert Magda Palmer has completed the mammoth task of matching gemstones and minerals to the celestial bodies of our solar system, correlating astronomical facts with gemmological research.. Her matches align with newly discovered, scientifically recognized facts in astronomical and gemmological research in order to give credence to accepted facts. Each gemstone, rock, and crystal has a unique energy directly linked to its chemical composition and internal structure, just as the celestial bodies that influenced our time of birth emit cosmic forces gained through their inherent state of being. With our appropriate birthstones we can focus ourselves, enhance our positive objectives, and travel our Tao taking the most exhilarating paths. Practical and grounded in a deep love of the subject, this guide offers a valuable resource for practitioners of alternative medicine using gemstones and minerals as a medium in healing. A powerful and positive book anchored in sound knowledge and research. An enduring classic text it offers humanity valuable insights for healing and vibrant well-being.
