Lapis lazuli or azure stone is an opaque semi-precious stone with an intense azure blue color. It is not a mineral but a rock, because it consists of more than one component. It is mainly mined in Afghanistan. The main component of lapis lazuli is lazurite (25% to 40%), a feldspar substitute with the chemical formula (Na, Ca) 8 (AlSiO4) 6 (S, SO4, Cl) 1-2. [1] Other important components are: calcite (white), sodalite (blue) and pyrite (yellow - metallic shiny). Furthermore, the minerals augite, diopside, enstatite, micas, hauynite, hornblende, geyerite (a sulfur-rich variety of lollinite) and nosane can also occur in lapis lazuli.
