Calcite CaCO3.Lazurite is a popular but generally expensive mineral. Well-formed, deep blue crystals are rare and valuable. It is more commonly found massive and combined with other minerals into a rock called lapis lazuli. Lapis lazuli or lapis for short is mostly lazurite but commonly contains pyrite and calcite and some other minerals. The name means “blue rock” and is always a brilliant blue with violet or greenish tints. The rich blue colour is due to the sulfur that is inherent in the structure of lazurite. Small crystals of pyrite are always present in lapis and their brassy yellow colour is both attractive and diagnostic in distinguishing lapis from its also blue cousin – sodalite rock, which lacks pyrite.
