Polished Sodalite Pocket Stone - Choose your quantity! Uniqueness Guaranteed: Every item is one-of-a-kind, making them ideal for all projects or designs. Avg Size: (1.6 Inches Diameter) Sizes Vary Slightly Sodalite is a silica-based mineral with a high concentration of sodium. While the bulk of the stone is a royal blue often used in paint pigment, it can also contain inclusions of calcite and quartz, resulting in white streaks. While it is commonly mistaken for lapis lazuli, sodalite does not contain any pyrite inclusions the way lapis does, and any orange or brown inclusions are typically feldspar. Sodalite that contains especially large amounts of quartz is sometimes called sodalitic quartz. Handmade items vary in size, shape, and color when selected randomly (the highest quality items are chosen first). They'll be as beautiful as those in the photos.
