Review & Description
"Collecting Rocks, Gems & Minerals" focuses on the areas of collecting, identifying and determining the worth of rocks, minerals and gemstones; how and where collectors can acquire them; and, what they can do with them once excavated. Whereas most rock books require the reader to have a background in geology to find the appropriate chapter, this title is organized by visual characteristics such as color, texture, crystal shape, etc., rather than by chemical composition. With 1,000 beautiful color pictures, readers can see the visual detail they need to identify their rocks. Read more
