Whether buying gem-set jewelry or loose stones, you will be faced with a colorful array of beauty and value. With such a wide choice - from amethyst to zircon - which should you choose? What is it worth, and how do you even know it is real? All that glitters is not gold, as they say, and all that sparkles is not diamond. Gemstones helps to answer these questions in simple and easy to understand terms. As well as diamonds, emeralds, rubies and sapphires, over 100 gems are featured, with full descriptions, technical details, and tips on how to check for fakes. The book is illustrated throughout with fabulous color photographs to make identification easier. Technical terms such as refraction and fluorescence are explained and some basic identification tests are introduced. A helpful tour around the world details where gems are best available. Informative appendices include a glossary of terms, tables of specific gravity and refractive index, and the comparative value of different stones. The clear, uncomplicated presentation makes this book a must for anyone interested in gemstones, whether as an investment or simply as a hobby.
