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.

Download or read book Sapphire written by Elena R. Dobrovinskaya and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the second half of the twentieth century, a new branch of materials science had come into being — crystalline materials research. Its appearance is linked to the emergence of advanced technologies primarily based on single crystals (bulk crystals and films). At the turn of the last century, the impending onset of the “ceramic era” was forecasted. It was believed that ceramics would play a role comparable to that of the Stone or Bronze Ages in the history of civilization. Naturally, such an assumption was hypothetical, but it showed that ceramic materials had evoked keen interest among researchers. Although sapphire traditionally has been considered a gem, it has developed into a material typical of the “ceramic era.” Widening the field of sapphire application necessitated essential improvement of its homogeneity and working characteristics and extension of the range of sapphire products, especially those with stipulated properties including a preset structural defect distribution. In the early 1980s, successful attainment of crystals with predetermined char- teristics was attributed to proper choice of the growth method. At present, in view of the fact that the requirements for crystalline products have become more str- gent, such an approach tends to be insufficient. It is clear that one must take into account the physical–chemical processes that take place during the formation of the real crystal structure, i.e., the growth mechanisms and the nature and causes of crystal imperfections.

Download or read book Surface Studies of Heat treated Natural Rubies and Sapphires written by Supakit Achiwawanich and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat treatment of ruby and sapphire has been extensively practised in order to enhance their visual appearance. Even though research on the bulk properties of the gemstones has been performed comprehensively, surface studies of heat-treated natural ruby and sapphire are very limited. The aims of this thesis are: to demonstrate potential capacities of non-invasive surface techniques including X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) on the natural Mong Hsu ruby and Kanchanaburi sapphire, and to elucidate surface effects after heat treatments in different atmospheric conditions commonly practised in the commercial arena. Preliminary studies using cathodoluminescence (CL) and X-ray computerised tomography (XCT) on heat treated gemstones are also given in the thesis.
Download or read book The Physics and Chemistry of Color written by Kurt Nassau and published by Wiley-Interscience. This book was released on 2001-07-27 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: An updated and revised second edition of the acclaimed classic Have you ever wondered why the sky is blue, or a ruby red? This classic volume studies the physical and chemical origins of color by exploring fifteen separate causes of color and their varied and often subtle occurrences in biology, geology, mineralogy, the atmosphere, technology, and the visual arts. It covers all of the fundamental concepts at work and requires no specialized knowledge. Author Kurt Nassau includes hundreds of illustrations, tables, and photographs-as well as end-of-chapter problems-that aid in visualizing the concepts discussed. An updated bibliography permits readers to pursue their own particular interests and an expanded series of appendices cover advanced topics. The Physics and Chemistry of Color, Second Edition is a one-of-a-kind treatment of color that provides both detailed physical and chemical properties of color and a more general overview of the subject. It will prove highly useful to specialists and non-specialists alike-and fascinate those with varied interests from optics to art history.
Download or read book The Book of Ruby and Sapphire written by J. F. Halford-Watkins and published by . This book was released on 2012-01-01 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prior to the 1930s, ruby and sapphire were mysteries, arcane gems oft-confused with spinel and other look-alikes. Enter Col. J.F. Halford-Watkins. Living in Mogok, Burma for more than two decades, he penned several articles and an entire monograph on the subject of these rare gems. Sadly he passed away before it could be published. In 1994, Richard Hughes came across a reference to the manuscript. Patrick Streeter, grandson of G. Skelton Streeter, and great grandson of the famed London jeweler, Edwin Streeter, had mentioned the Halford-Watkins manuscript while writing his book, Streeter of Bond Street. Following up on that obscure reference Richard Hughes stumbled upon something truly fantastic, an undiscovered treasure of the gemological literature. Over ten years in the making, The Book of Ruby & Sapphire is the realization of Halford-Watkins' vision. Professionally edited and illustrated, it represents a gemological tour de force.

Book excerpt: An instant #1 New York Times Bestseller and a USA Today and Indie Bestseller! The Stormlight Archive saga continues in Rhythm of War, the eagerly awaited sequel to Brandon Sanderson's #1 New York Times bestselling Oathbringer, from an epic fantasy writer at the top of his game. After forming a coalition of human resistance against the enemy invasion, Dalinar Kholin and his Knights Radiant have spent a year fighting a protracted, brutal war. Neither side has gained an advantage, and the threat of a betrayal by Dalinar’s crafty ally Taravangian looms over every strategic move. Now, as new technological discoveries by Navani Kholin’s scholars begin to change the face of the war, the enemy prepares a bold and dangerous operation. The arms race that follows will challenge the very core of the Radiant ideals, and potentially reveal the secrets of the ancient tower that was once the heart of their strength. At the same time that Kaladin Stormblessed must come to grips with his changing role within the Knights Radiant, his Windrunners face their own problem: As more and more deadly enemy Fused awaken to wage war, no more honorspren are willing to bond with humans to increase the number of Radiants. Adolin and Shallan must lead the coalition’s envoy to the honorspren stronghold of Lasting Integrity and either convince the spren to join the cause against the evil god Odium, or personally face the storm of failure.
