Discovered in Greenland in 1806, sodalite did not become an important ornamental gemstone stone until 1891 when large deposits of gem-quality material were discovered in Canada. Sodalite is a blue stone interspersed with white calcite. It comes in a very narrow range of colors from dark blue to a violet blue, often with white, yellow or red veining. It is sometimes confused with lapis lazuli, as it also has small specks of pyrite in it. The largest deposit of sodalite is in Brazil.
Sodalite is the stone of athletes, as it stimulates endurance. It is said sodalite will harmonize the inner being or the conscious and subconscious mind. It is also said to promote peace and harmony, and is thought to be extra lucky for writers.
Sodalite is rated at 5 to 6 on the Mohs scale of hardness. It should be worn and stored with some care to avoid any permanent damage to the stone.
