The name is international, from the Latin, lapis, which means stone, and from the Arabic, azul, which means blue. It literally means "blue rock" and is actually a rock rather than a mineral. It is composed of a highly variable mixture of the minerals lazurite, pyrite and calcite. The best Lapis Lazuli is uniformly deep blue in color, being opaque to semi-translucent and consist almost totally of lazurite.
In addition to lazurite, specimens of lapis lazuli usually contain calcite and pyrite. Sodalite, hauyne, wollastonite, afghanite, mica, dolomite, diopside, and a diversity of other minerals might also be present. To be called "lapis lazuli," a rock must have a distinctly blue color and contain at least 25% lazurite.
Chemical formula: (Na,Ca)8(AlSiO4)6(S,Cl,SO4,OH)2; Mohs Hardness: Varies between the 3 of calcite and the 5 to 5.5 of lazurite.
