Sodalite is a deep blue feldspathoid mineral, celebrated for its rich coloration and cloudy white veining. It forms in silica-deficient igneous environments like nepheline syenite, typically appearing in massive form rather than well-defined crystals. The mineral’s vitreous to greasy luster lends a subtle gleam, offset by its characteristic white streak and uneven to conchoidal fracture. Notably, sodalite exhibits UV reactivity—glowing pink when exposed to ultraviolet light—adding a luminous charm to its already striking appearance.
