Sodalite is a chloric sodium aluminum silicate with a hardness of 5.5 to 6. The name refers to its sodium content. Sodalite’s crystal system is isometric, formed of rhombic dodecahedra. It is rare for sodalite to form crystals and appears most often in massive or granular habits. Sodalite is primarily blue or gray but can be white, yellowish, reddish, or greenish. The blue shades of Sodalite are found intermingled with white Calcite.
