Lazurite is a deep blue mineral that is primarily found in the rock known as lapis lazuli. It is a member of the sodalite group and is composed mainly of sodium, aluminum, and sulfur. Lazurite is prized for its vibrant color, which is often used in jewelry and decorative items. This mineral is typically formed in metamorphic rocks and is often associated with other minerals like calcite and pyrite. Lazurite has been used since ancient times, particularly in Egyptian artifacts, where it was ground into powder for use as a pigment in paintings and cosmetics.
