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.

Book Description
First published in 1848, authored by J.D. Dana, the Manual of Mineral Science now enters its 23rd edition. This new edition continues in the footsteps or its predecessors as the standard textbook in Mineralogy/Mineral Science/Earth Materials/Rocks and Minerals courses. This new edition contains 22 chapters, instead of 14 as in the prior edition. This is the result of having packaged coherent subject matter into smaller, more easily accessible units. Each chapter has a new and expanded introductory statement, which gives the user a quick overview of what is to come. Just before these introductions, each chapter features a new illustration that highlights some aspect of the subject in that particular chapter. All such changes make the text more readable, user-friendly and searchable. Many of the first 14 chapters are reasonably independent of each other, allowing for great flexibility in an instructor's preferred subject sequence. The majority of illustrations in this edition were re-rendered and/or redesigned and many new photographs, mainly of mineral specimens, were added. NEW Thoroughly Revised Lab Manual ISBN13: 978-0-471-77277-4 Also published by John Wiley & Sons, the thoroughly updated Laboratory Manual: Minerals and Rocks: Exercises in Crystal and Mineral Chemistry, Crystallography, X-ray Powder Diffraction, Mineral and Rock Identification, and Ore Mineralogy, 3e, is for use in the mineralogy laboratory and covers the subject matter in the same sequence as the Manual of Mineral Science, 23e.

Book Description
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.

Book Description
This book provides a comprehensive review of gem corundum origins worldwide, highlighting the enduring value of rubies and sapphires despite synthetic alternatives. By delving into natural corundum origins and associated minerals, this knowledge boosts corundum prices and intensifies market trade. The book explores formation conditions and key evidence such as trace elements, mineral inclusions, and stable isotopes. These findings elucidate corundum’s origin, linking to the rock types and geological occurrences. Drawing from high-impact journals, books, and the author’s research, it offers valuable insights into synthetic processes and treatments. Catering to mineralogists, geologists, gemmologists, students, and gem traders, the book serves as a valuable reference for identifying gemstone origins. Its rarity in the market makes it particularly valuable for enthusiasts and professionals. As researches in this field continue to grow, this book bridges the gap by making complex terminology accessible to a wide audience.
