Sodalite has a cubic crystal system and is in the mineral class of lattice silicate. It is mainly formed in a primary manner in pegmatites that are low in silica, and most often found in cavities of volcanic rock.
Its coloring is primarily blue with white, colorless, and sometimes violet or pink feldspar veins. The blue hue can sometimes be confused with Lapis Lazuli. While both have the same cubic structure, and both are lattice silicates, the Sodalite does not have any iron.
