US$27.99

Newly published in a fifth edition, this definitive guide takes the mystery out of appreciating, buying, and selling gemstones. It covers everything from the romance and history of more than 1,800 gemstones to their geographic locations; scientific, physical, and color properties; and the way they are formed, structured, and mined. The book also fully covers the optical features of gems, light, and color, luminescence, refraction and inclusions, and key information about the densities and chemical elements of each stone, with fascinating details on different cuts, polishing, gems, hardness, cleavage, classification, trade names, rarity and more!
