Book Description
East Africa is famous for its world-class gemstones and mineral specimens, most notably the highly sought-after blue tanzanite, found only in Tanzania in a very small area in the northeast. Many other minerals and gemstones are mined in the region and this is the first publication to showcase and examine those occurring in the five countries that make up East Africa – Kenya, Tanzania, Rwanda, Uganda and Burundi. 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 Description
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."

Book Description
From the dawn of time, ruby and sapphire have both attracted and fascinated humans in ways that few other items could.While objects of desire are found throughout the natural world, physical beauty is too often ephemeral. From the allure of a man, woman, flower or butterfly, through the fleeting moments of a sunset, there is little that lasts and practically nothing that can be passed down to our descendants. The exception is precious stones. Not only are they the most durable creations of mother nature, but their visual splendor is truly eternal.In this companion to his 2013 book, Ruby & Sapphire--A Collector's Guide, Richard Hughes examines these gems from the gemological standpoint, delving into these gems not just from the aesthetic, but also from the scientific point of view.The product of nearly 40 years of firsthand experience, it covers every aspect of the subject from A-Z. History, sources, prices, quality analysis, synthetics and treatments, everything is here. Ruby & Sapphire--A Gemologist's Guide represents the most comprehensive book ever written on a single precious stone. With over 1000 photos, maps and illustrations and 3500 references, it is nothing less than a tour-de-force of gemological scholarship.
