Book excerpt: 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.

Book Synopsis Russian Alexandrites by : Karl Schmetzer
Download or read book Russian Alexandrites written by Karl Schmetzer and published by . This book was released on 2010 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alexandrite, a variety of chrysoberyl, and one of the finest colour-change natural gemstones, may almost be called "the national gemstone of Russia". This great prestige is based on two facts: its noble name in honour of the Tsarevich Alexander Nikolaevich (the future Tsar Alexander II) and its dazzling colours, green in daylight and red in incandescent light, the military colours of Imperial Russia. Although quantities of facetable quality alexandrite are considerably less than those of emerald, alexandrite is counted among and compared to the "big four" of the gem business: diamond - ruby - sapphire - emerald. In this book the authors present an historical overview of emerald mining in the Urals, the discovery of Russian alexandrites in the Uralian emerald mines, the naming and historical use of alexandrites and their appearance and display in mineralogical museums and the gem trade. Morphology and twinning of rough alexandrite is described for single crystals, single contact twins and cyclic twins (trillings). Mineralogical and gemmological properties are thoroughly explained and numerous photo-micrographs of inclusions and growth patterns in faceted samples are presented. Chatoyancy and asterism of alexandrite and chrysoberyl from Russia and Sri Lanka are also described. A further chapter deals with characteristic growth patterns of Russian, other natural and synthetic alexandrites. Colorimetric data of Russian alexandrites and green chrysoberyls are explained using the CIELAB colour space, and the distinction between these varieties is explained. A chapter on trace element chemistry and locality determination rounds off the book. An extensive appendix containing lists of historical names, a time table and numerous references provides valuable information on Russian alexandrites for all researchers in the mineralogical and gemmological fields as well as for gemmological laboratories, jewellers and gem dealers. Consequently, this book, illustrated with more than 200 colour figures and photographs, addresses mineralogists, gemmologists, historians, mineral and gem collectors as well as all members of the gem trade.

Chapters in the section on clarity treatments cover laser-drilled and glass-filled diamonds. Material is presented in chronological order to help readers follow the evolving areas of interest and understanding of these treatments. Some of the older material includes editorial comments to explain now-unfamiliar concepts or discuss significant development since the original publication. The book includes a poster-sized color chart enclosed in a side pocket, with color photos demonstrating diagnostic features of filled diamonds and testing techniques.
