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.

Understanding gemstones in a geological context Gemstones are colorful treasures of the Earth that have captivated humans for thousands of years. The physical and chemical characteristics of each type of gem provide insights into the geological processes that created them. Geology and Mineralogy of Gemstones is a textbook aimed at upper-level undergraduate and graduate students. It presents the basic mineralogical and geological knowledge needed to understand gemstones and examines the characteristics and geological origins of different types of gemstone. Volume highlights include: Concepts in mineralogy Structure and chemical composition of minerals Geological processes that lead to the formation and movement of gemstones Equipment and tools used to examine gemstones and their physical properties The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

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.

The Fundamentals of Mining for Gemstones and Mineral Specimens provides the basics that every gem miner needs to know for a successful small mining venture. The author includes a wide range of details he has learned from his varies career throughout the world as a contract miner and geologist. The chapters are presented in a practical order beginning with the geology of different gem and mineral deposits, how to follow the signs, the importance of mapping, the necessary equipment, the use of explosives, practical mining, first aid for miners, tips for working in developing countries, and working with government agencies like the ATF and MSHA. The reader will particularly appreciate the eight case studies which dal with a variety of gem deposits, and the concerns and challenges presented by each. The rich illustrations add value to this 400-page volume.

Gems have been used in the manufacture of jewellery and as ornaments since antiquity. Considering gems, recent statistics have shown that about 15 billion Euros are annually at stake. Nowadays, gemmology, i.e., the study of gem materials, is one of the most expanding fields in the earth sciences, positioned between academia and industry. As an applied science, in gemmology, the instruments used should be non- or microdestructive, and their cost should be reasonable both in terms of equipment and time consumption. Gemmology can also be used contribute to the development of pure science and in some cases, destructive techniques may have to be used. Taking into account the fact that gems are albeit rarely available for scientific research, this compilation of 20 articles by around 100 researchers from over 30 different institutions situated in 20 countries from around the globe, presented in the Special Issue entitled “Mineralogy and Geochemistry of Gems”, offers very good examples on the application of various methods for their study which will hopefully contribute to our better understanding of gem formation in general and will enhance scientific debates attracting more scientists from various disciplines to get involved in this field.

This report is a preliminary compilation of ongoing work regarding the geology and geochemistry of gemstone deposits and applicable exploration criteria. Its objective is to provide information on gemstone deposit geology and general guidelines on identifying and exploring for gemstones. The report focuses on a selection of the most valuable gemstones in the global gem trade (excluding diamonds): ruby, sapphire, emerald, chrysoberyl, tsavorite garnet, tanzanite, and the gem minerals found in pegmatites or rhyolites (topaz, aquamarine, tourmaline). For each gem mineral, background information is introduced and the physical and chemical characteristics of the mineral are described. The geology and genesis of each gem deposit type is summarized and exploration guidelines listed. The final chapter discusses application of the exploration criteria to Yukon geology.

Victoria is often seen as the forgotten state when it comes to gem minerals. The history of gems in Victoria is inextricably linked to the discovery of gold in 1851. In 1854, George Milner Stephen publicised for the first time, the discovery of gems in Victoria. These included blue and white sapphires from Ballarat diggings and rubies, topaz and garnet from the River Ovens in northeast Victoria. In 1857, well-known German natural historian Ludwig Becker reported that these same gems could also be found where there was gold.
