Sodalite is a rare rock-forming mineral best known for its blue to blue-violet color. It has a chemical composition of Na4Al3Si3O12Cl and is a member of the feldspathoid mineral group. High-quality sodalite is used as a gemstone, a sculptural material, and an architectural stone.
Sodalite occurs in igneous rocks that crystallized from sodium-rich magmas. This is the origin of the name "sodalite." These magmas also contained so little silicon and aluminum that quartz and feldspar minerals are often absent. Sodalite-bearing rocks include nepheline syenite, trachyte, and phonolite. These types of rocks are so rare that most geologists never see them in the field.
