One-of-a-kind natural blue quartz. You will receive a piece similar to those shown. Size: 3 to 6 inches (sizes vary) Blue quartz is a variety of quartz, a common silicon dioxide mineral. It forms in igneous and metamorphic environments as silica-rich fluids crystallize over time. Its blue coloration is caused by inclusions of minerals such as crocidolite or tourmaline within the quartz structure. These bookends typically show a massive crystalline structure with a translucent to opaque appearance, often featuring subtle color variation and a polished face contrasted with a natural outer surface. Each item is unique in shape, color, and pattern. Higher-grade pieces are selected first. Photos represent overall quality and appearance.
