Gemstones, Paperback by O'Donoghue, Michael, ISBN 940107030X, ISBN-13 9789401070300, Like New Used, Free shipping in the US 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 gemstons 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 th all the journals and monographs in the field have been consulted so that th 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 referenc 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 ths on which the line illustrations are based. The colour plates present in th derive from a number of sources, which I would like to acknowledge as follows.
