From the dawn of time, ruby and sapphire have both attracted and fascinated humans. 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 them 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.

Gemology

This edition has been revised and expanded to reflect recent and varied developments in the highly specialized field of gemology. Among these are: gemstone synthesis; imitation gems; the alteration of gems to improve, add, remove or otherwise change their color, phenomena or clarity; the importance and widespread uses of the microscope to reflect the aforementioned developments; and a number of new gem minerals or new forms of previously described minerals recently discovered or actively marketed for the first time. The chapter on Descriptive Gemology has been divided into two groups: important gemstones (those gem materials most widely used in jewelry and ornamental objects) and less important gemstones (those less commonly encountered).
