The study of rocks, minerals, and gemstones is fascinating in itself and casts important light on numerous other subjects, including chemistry, medicine, metallurgy, geology, and paleontology. Even business studies, economics, and politics may be illuminated by a knowledge of the valuable ores that form the basis of the wealth of many nations.
This ideal introduction of the fascinating world beneath our feet looks in detail at nearly 300 rocks, minerals, and gemstones. Each entry describes how the material is formed, where it is formed, what is made of, and how it relates to other naturally occurring substances. There is also a wealth of information about mining techniques, industrial applications, gem-cutting methods, astrological significance, myths, and legends.
Each entry is illustrated with beautiful color photographs, and pages are color coded so that readers can see at a glance whether each substance is a rock, mineral, or a gem.
