Sodium aluminum silicate with chlorine, 5.5 to 6 hardness. Sodalite is so named in allusion to its sodium content and is used as a semi-precious gemstone. Great for carvings, beads, and other lapidary work. Sodalite was first discovered in 1806 in Greenland. Vast deposits of fine sodalite was discovered in Ontario, Canada in 1891. Sodalite typically forms in massive formations as vein fillings in plutonic igneous rocks such as nepheline syenites. It is associated with other minerals typical of undersaturated environments, namely leucite, cancrinite and natrolite.
