Description
Over 100 vivid color photographs showcase the diverse beauty of feldspar minerals in their natural geological context. As a group, they make up nearly sixty percent of the earth's crust and can be found in various locations worldwide, often forming stunning gem crystals.
This comprehensive guide explains how feldspars are formed, including the complex structural features that create fine crystals, twins, and vibrant colors. Detailed entries for each mineral provide locality information and full-color photos to help collectors identify good specimens and associate them with other minerals.
