Synopsis
Gems - History, Identification, and Evaluation - takes readers on a journey into the world of gemology with a clear, rigorous, and useful approach, halfway between science and wonder.The book teaches how to identify a gem, understand its nature, and confidently distinguish between natural, synthetic, and imitation materials. It covers the entire process, from the basics of identification (observation, tools, optical indices, density, fluorescence, spectroscopy, and laboratory methods) to professional and commercial evaluation. Each chapter is dedicated to a different gem, from the most famous ones such as diamonds, rubies, sapphires, and emeralds, to rarities of great collector's interest. The chapters follow a set pattern: history, origin, physical and optical properties, diagnostic criteria, treatments, use in jewelry, and quality parameters.The book is aimed at students, professionals in the sector, and anyone who wants to make informed purchases. It uses technical but accessible language and proposes a method that can be applied systematically. It is not enough to know how beautiful a gemstone is: it is essential to understand what you are looking at, how to verify it, and what its real value is.
