This vintage book contains a collection of articles on the creation and composition of diamonds. The contents of this volume originated from a series of lectures delivered by Henry Carvil Lewis, M.A., F.G.S., which were later edited and arranged by Professor T. G. Bonney. "Papers and Notes of the Genesis and Matrix of the Diamond" will appeal to those with an interest in mineralogy and would make for a fantastic addition to collections of allied literature. Contents include: "Paper Read in 1886", "On a Diamond-Bearing Peridotite and on the History of the Diamond", "The Matrix of the Diamond", "Paper Read in 1887", "Kimberlite From the Unites States", and "Note". Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern edition complete with a specially commissioned new introduction on metal work. First published in 1897.

First published in 2001, Barren Lands is the classic true story of the men who sought—and found—a great diamond mine on the last frontier of the far north. From a bloody 18th-century trek across the Canadian tundra to the daunting natural forces facing protagonists Chuck Fipke and Stewart Blusson as they struggle against the mighty DeBeers cartel, this is the definitive account of one of the world’s great mineral discoveries. Combining geology, science history, raw nature, and high intrigue, it is also a tale of supreme adventure, taking the reader into a magical—and now fast-vanishing—wild landscape. Now in a newly revised and updated edition.

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.
