DOWNLOAD EBOOKFrom 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 EBOOKPrior 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.
