Sodalite is an opaque, blue-white silicate of alumina and soda with some chlorine (sodium aluminum silicate and sodium chloride). Its name reflects its sodium content.
Sodalite is found in all shades of blue and is a major constituent of the rock lapis lazuli. It is a very scarce mineral that can be rock-forming. Sodalite is used for carvings and in some jewelry pieces. Its light to dark pure blue color is well-known in the semi-precious stone trade.
Sodalite is found in Brazil, Canada, India, Italy, Namibia, the United States, and Russia.
