Geology / History

A light, relatively hard yet fragile mineral Sodalite is named after its sodium content. In mineralogy it may be classed as a feldspathoid. Well known for its rich royal blue colour, Sodalite may also be grey, yellow, green or pink & is often mottled with white veins or patches.

Although somewhat similar to lazurite & lapis lazuli, sodalite rarely contains pyrite which is a common inclusion in lapis. Its blue colour is more like traditional royal blue rather than ultramarine. It is further distinguished from similar minerals by its white, rather than blue streak. Sodalite's six directions of poor cleavage may be seen as incipient cracks running through the stone. 

Sodalite’s rich royal blue is widely enjoyed as an ornamental gemstone. Although massive sodalite samples are opaque, crystals are usually transparent to translucent. Discovered in 1811 in the Ilimaussaq intrusive complex in Greenland, sodalite did not become important as an ornamental stone until 1891 when vast deposits of fine material were discovered in Ontario, Canada.
