Book excerpt: Follow in the footsteps of successful gem and gold hunters and search the hills for rough diamonds, colored gemstones, lapidary minerals, precious metals and interesting minerals and rocks. Written for the geoscientist, prospector and rockhound; the first part of the book focuses on physical characteristics of gems and minerals. This is supplemented with the second part of the book that describes dozens upon dozens of colored gem, diamond, gold, mineral and rock localities using the Public Land Survey System and GPS coordinates so the reader can visit these sites on a home computer with aerial and satellite imagery to gain an understanding of what to look for in the field. With these same coordinates, the reader can visit some occurrences, deposits and areas suggested for prospecting to further their gem hunter prospecting education and potentially lead to new discoveries. Now you can learn what to look for when searching for Mother Nature's treasure.
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.

Book excerpt: Excerpt from Guide Collection of Gemstones: Museum of Practical Geology The minerals in the Museum of Practical Geology are arranged for the most part according to their commercial applications and, in consequence, the ores, i.e., minerals used for the extraction of metals, are separated from the so-called non-metallic minerals or those which, in general, are not applied to such a purpose. This arrangement has, of course, no scientific basis and fails to bring out the relationships between the various species, but it possesses the advantage of showing in a compact and readily accessible way those minerals which concern commercial and mining men. The non-metallic minerals are arranged in cases, marked A - X. The term non-metallic is somewhat misleading, as nearly all the minerals to which it is applied contain a metal or metals. These, however, are usually the light metals, e.g., aluminium, calcium, magnesium, potassium, sodium, as distinguished from the heavy metals of commerce, such as copper, tin, silver, gold, lead, &c. Amongst the non-metallic minerals gemstones occupy an important place from the point of view of commercial and general interest. They have not been separated from the rest of the minerals of this class, and the visitor will find them distributed throughout the various divisions. The reason for this is that in the majority of cases gemstones show no natural relationships with one another, the only feature which unites them into a class being their suitability for purposes of adornment. This suitability depends mainly on beauty and durability, but all minerals possessing these qualifications would not be reckoned as gemstones by a dealer. Many stones possessing these qualities in a high degree have little or no value at the present time, for there is a wide distinction between a stone naturally fitted for the purposes of the jeweller, and one for which there is a demand. From the commercial point of view the really precious stones are diamond, ruby, sapphire, emerald, and, perhaps, opal and turquois. (The pearl, although probably the most valuable gem at the present time, is excluded, as it can hardly be termed a mineral.) The demand for the first four of these is fairly constant and the value is always high for good specimens. The fashion of the moment dictates the value of the other minerals which legitimately claim a place amongst gemstones. At one time it may be tourmaline, at another, chrysolite, at another, cat's-eye, or aquamarine, or topaz, or zircon, which is in vogue; the favoured gem consequently rises in value until some new whim relegates it to comparative obscurity. To such stones the term "semi-precious" is sometimes applied. The element of rarity plays, perhaps, the most important part in determining the value of a gemstone and outweighs, by what often seems a disproportionate amount, considerations of beauty and of durability.

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.
