Lapis lazuli /ˈlæpɪs ˈlæzʲuːli/, /-ˈlæzʲuːlaɪ/, or lapis for short, is a deep blue semi-precious stone prized since antiquity for its intense color. Lapis lazuli was mined in the olden Aperture mines.


Lapis lazuli is a rock whose most important mineral component is lazurite[9] (25% to 40%), a feldspathoid silicate mineralwith the formula (Na,Ca)8(AlSiO4)6(S,SO4,Cl)1-2.[10] Most lapis lazuli also contains calcite (white), sodalite (blue), and pyrite(metallic yellow). Other possible constituents: augite; diopside; enstatite; mica; hauynite; hornblende, and nosean. Some lapis lazuli contains trace amounts of the sulfur-rich löllingite variety geyerite.

Lapis lazuli usually occurs in crystalline marble as a result of contact metamorphism.
