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
"Scientific Investigation of Copies, Fakes and Forgeries is a comprehensive guide to the technical and scientific study of the authenticity of a wide range of antiquities and artworks. It is the first book to provide a full survey of the subject of forgery from a scientific basis, examining a wide range of materials and techniques." "The demand for copies, fakes and forgeries is driven by rising prices in an international marketplace. The book examines the available new technologies and ever more sophisticated forging techniques, looking at production and distribution of fraudulent artworks. The subject is exemplified by numerous internationally based case studies, some turning out not to be as conclusive as is sometimes believed." "The book is aimed at those who need to understand the available approaches to and methods of scientific and technical authentication, be they curator, collector, conservator or scientist." --Book Jacket.
