Sodalite is a tectosilicate mineral. It is part of the cubic crystal system and has a waxy luster. It is also part of the sodalite group with other stones like lazurite and hauyne. Sodalite has an opaque transparency and is a rock forming mineral too. It comes in shades of royal blue and purple with white calcite.
