Sodalite is a rich blue ornamental mineral originally discovered in Greenland in 1806. The name Sodalite reflects the stone’s sodium content. Sodalite is found in all shades of blue. It is a major constituent of the rock lapis lazuli, so the two are easily confused. However, unlike lapis azuli, sodalite very rarely contains brassy pyrite specks. Even with this difference however, sodalite is used frequently as a substitute for the more rare and expensive lapis azuli. Sodalite gained notoriety in the 1800’s during a royal visit to Bancroft, Canada by Princess Margaret of England. The princess fell in love with the mineral and chose it as interior decoration for the “Marlborough House” . For this reason, sodalite from that Canadian area is sometimes called Princess Blue.
