One-of-a-kind natural sodalite. You will receive a piece similar to those shown. Size: 5 to 6 inches (sizes vary) Sodalite is a sodium-rich silicate mineral commonly found in igneous rocks such as nepheline syenite. It forms as magma cools and crystallizes in silica-poor environments. Its deep blue color is caused by the presence of sulfur within the crystal structure, often accompanied by white calcite inclusions. These specimens typically display a massive structure with mottled blue and white patterns, and are mounted on a metal stand to highlight the natural formation. Each item is unique in shape, color, and pattern. Higher-grade pieces are selected first. Photos represent overall quality and appearance.
