Description: Opaque mottled blue stone, often with bits of white in it

Sodalite Sodalite is a lovely blue, and quite common. It is sometimes used as a substitute for Lapis Lazuli in jewelry, although good Lapis Lazuli is a much richer blue.

A quantity of Sodalite was sent to Denmark from Greenland during the Napoleonic Wars. It was captured by the British however, and examined by a Glasgow chemist, Professor Thomas Thomson, who named it after its sodium content.
