Lapis lazuli is one of the metamorphic rocks used as a semiprecious stone and has been known since ancient times. Its name derives from the Latin “lapis”, stone, and from the Arabic “läžwärd“, blue. It has a blue color, given by the high content of lazurite, and golden shades, given by the inclusions of pyrite.
