This ninth edition, published by Butterworths, represents decades of expertise from the former Director of the Gem Testing Laboratory of the London Chamber of Commerce. Anderson's comprehensive text covers every aspect of gem testing, from the origin and recovery of gemstones to detailed chapters on individual stones including diamond, ruby, sapphire, emerald, aquamarine, topaz, tourmaline, garnets, opals, and many more. The book also covers synthetic and imitation stones, composite stones, and the full range of identification techniques including crystal structure, hardness, cleavage, specific gravity, refractive index, spectroscopy, luminescence, microscopy, and X-ray testing. The book is illustrated with diagrams and includes extensive identification tables and appendices. This is an indispensable resource for professionals and serious students of gemology. Essential reading for anyone seeking to master the science of gem identification.''
