In the middle of New York City lies a neighborhood where all secrets are valuable, all assets are liquid, and all deals are sealed with a blessing rather than a contract. Welcome to the diamond district. Ninety percent of all diamonds that enter America pass through these few blocks, but the inner workings of this mysterious world are known only to the people who inhabit it. In Precious Objects, twenty-six-year-old journalist Alicia Oltuski, the daughter and granddaughter of diamond dealers, seamlessly blends family narrative with literary reportage to reveal the fascinating secrets of the diamond industry and its madcap characters: an Elvis-impersonating dealer, a duo of diamond-detective brothers, and her own eccentric father. With insight and drama, Oltuski limns her family’s diamond-paved move from communist Siberia to a displaced persons camp in post–World War II Germany to New York’s diamond district, exploring the connections among Jews and the industry, the gem and its lore, and the exotic citizens of this secluded world. Entertaining and illuminating, Precious Objects offers an insider’s look at the history, business, and society behind one of the world’s most coveted natural resources, providing an unforgettable backstage pass to an extraordinary and timeless show.

This title is now in paperback for the first time.Artificial gemstones have been well established in the trade for some time, but now, following further refinements in their manufacture, gemmologists worldwide are facing increasing problems with identification.Today, gem-quality synthetic diamonds, once deemed impossible to produce, are becoming widely available, and, moreover, it is possible to create almost any major gemstone in whatever colour is desired. Then, too, the growth of diamonds by chemical vapour deposition is destined to present further problems. The synthetic products of the past, particularly of the 1960s, are still available, and are puzzling the newer generations of gemmologists who have not encountered them previously.In "Artificial Gemstones", Michael O'Donoghue provides the definitive guide to the various manmade substitutes thus enabling anyone handling gems to identify them accurately. Starting with the theory of synthetic gem manufacture and an explanation of the production methods used for growing and/or improving crystals - with their ornamental application - the book moves on to list and identify the materials themselves. Some of these have natural counterparts; others are new minerals and do not occur in nature. The author lists the identifying internal and external features and tests, and the book contains colour illustrations to display the inclusions found in transparent materials. The book is completed by an extensive bibliography and a useful appendix of trade names.Gemmologists, gem dealers, lapidaries, curators, amateurs and students of gemmology and mineralogy will all find this an indispensable addition to their bookshelves.
