Sodalite

Sodalite is a hard yet fragile mineral, named after its sodium content. The Royal Blue color of Sodalite is often mistaken for Lapis or Lazulite. However Sodalite is more of a Royal Blue than the Ultramarine color of the other two minerals. Sodalite rarely contains Pyrite which is often found in Lapis. Sodalite may also be grey, yellow, green, or pink and often contains white veins or patches. It is further distinguished from similar minerals by its white (rather than blue) streak.
