The book includes: An introduction to the fascinating geology of the region, including a map depicting underlying geology and mineral occurrence; detailed descriptions of minerals, including their gemological properties, history, occurrence and diverse uses across all spheres of life (from jewellery to numerous household items and even space-shuttle components); multiple full-colour photographs of each mineral and gem specimen. An invaluable reference for collectors, gemologists, students and anyone with an interest in the earth sciences. Sales points: A first, fascinating record of East African minerals and gemstones; numerous beautiful photographs of each mineral in full colour; concise, authoritative and accessible text.

Book excerpt: Since early 1989, a gem dealer I've known for years has been calling me every few weeks to brief me on mounting mayhem in Colombia's lucrative emerald market. The troubling gist of these calls is always this: There is a full-fledged turf war going on between that South American country's bustling drug and gem trades for control of its emerald ex port business. According to this dealer and several others, anywhere from two to four thousand emerald industry people, mostly miners and deal ers, have been murdered since 1980. No doubt the gem sector, itself never gun shy, has retaliated in full and in kind. After all, the two groups have banded together in an intermittent alliance against a common enemy-Communist guerillas-with results the CIA would envy. I mention this bloodshed because of something the gem dealer once said to me: "I bet you never think of what a gem has to go through to get to a jewelry store:' He's right. I tend to think of colored stones as things of beauty, not objects of gruesome power struggles between mining kingpins and drug lords. Can you blame me, or anyone with insider knowledge, if a gem sheds any connection with its past once sculpted by a cutter into the glittering mar vel we see in a jeweler's showcase? Like Odysseus listening to the sirens' song, we become victims of an aesthetics-induced amnesia.

Book excerpt: Tanzanite is one thousand times rarer than diamonds The first book ever presenting this precious stone discovered only forty years ago Upon the discovery of Tanzanite in Tanzania a specimen was entrusted to the stonecutter Manuel de Souza, who shared some samples with distinguished gemologists. While the prospector thought that he had found some sapphires, he was astonished to learn that he had unearthed something altogether extraordinary. The new gem immediately caught the eye of Tiffany & Co. Since 1968, the New York-based jeweler has pushed the stone into the spotlight. It launched a campaign that was successful enough to earn tanzanite the noble title of 'gem of the 20th century'. Tanzanite gained further renown when in 2002 the American Gem Trade Association (AGTA) named tanzanite, together with turquoise, the birthstones for December. Tanzanite's transformations have ultimately placed it alongside the most precious of precious gems. In short, tanzanite's age of glory has finally dawned. Needless to say, tanzanite's allure has attracted the attention of a list of famous designers: Lorenz Baumer (France), Ruth Grieco (Brazil), Catherine Sauvage (Germany), MVee (Hong Kong) and TTF (China). In Asia and elsewhere, tanzanite is seen as the source of happiness for the happy few. Tanzanite: Born from Lightning showcases hundreds of beautiful pieces of tanzanite jewelry, including superb creations made by Boucheron, Bulgari, Cartier, Chanel, Chaumet, Chopard, Dior, Boucheron, Louis Vuitton, Piaget, Van Cleef & Arpels, Wallace Chan and more."
