Discover the fascinating world of the treasures beneath your feet.
Minerals and Gemstones is a reference guide to 300 different minerals and gemstones, from simple sandstones to sanidine, jade and diamond. Learn what the Earth is made of, how its rocks were formed and how minerals and gems are used today.
Divided into sections covering the internationally recognised classification groups, Minerals and Gemstones offers a comprehensive overview of the many different types of natural gems and minerals – including native elements, sulphides, oxides, nitrates and silicates.
Each gemstone or mineral is illustrated with a clear and informative colour photograph, accompanied by accessible text and its chemical composition. For easy reference, each entry includes a table of information with colour, lustre, streak, hardness, specific gravity, cleavage, habit and the crystal system of each type of mineral and gemstone. The Minerals and Gemstones app is an essential, user-friendly reference work on the diversity of the Earth’s riches.
