Geology and Mineralogy of Gemstones by Elisha Price Pdf

A gemstone refers to a cut and polished piece of mineral crystal that can be utilized to create jewelry or other adornments. Gemstones are created underneath the surface of the Earth and may contain traces of other minerals known as inclusions. The majority of gemstones are found in alluvial gravels and igneous rocks but metamorphic and sedimentary rocks can also contain gem materials. Gemstones are classified into different species and groups on the basis of chemical composition and crystal structure. The most significant gemstone species include corundum, quartz, beryl, tourmaline and garnet. The majority of gemstones are hard but some soft minerals are also utilized in jewelry due to their luster or other physical qualities which hold aesthetic value. This book unravels the recent studies on the geology and mineralogy of gemstones. With its detailed analyses and data, it will prove immensely beneficial to professionals and students involved in the study of gemstones at various levels.

Mineralogy and Geochemistry of Gems by Panagiotis Voudouris,Stefanos Karampelas,Vasilios Melfos,Ian Graham Pdf

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.

Gemstones by Michael O'Donoghue Pdf

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.

Gemstones and Their Origins by P.C. Keller Pdf

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.
