Focus On Minerals introduces many common minerals and their gems. Texts and illustrations explain the physical properties useful in identifying different minerals. They include crystal structure (shape), color, streak (mineral powders), luster (appearance in reflected light), hardness, cleavage (breaks along planes of weakness) and others. Precious gems and gemstones hold significant interest throughout our history. Humans advanced their standard of living and culture by progressive uses of ore minerals and industrial minerals. Each of thirty plus minerals named in the book appears in a glossary with photograph and description.
