Specifications

Lapis lazuli is a rock, largely formed from the mineral lazurite.[3]
The main component of lapis lazuli is lazurite (25% to 40%

Lapis lazuli has been collected from mines in the Badakhshan province of Afghanistan for over 6,000 years and there are sources that are found as far east as in the region around Lake Baikal in Siberia. Trade in the stone is ancient enough for lapis jewelry to have been found at Predynastic Egyptian and ancient Sumerian sites, and as lapis beads at neolithic burials in Mehrgarh, the Caucasus, and even as far from Afghanistan as Mauritania.[2]

Lapis lazuli is a rock, largely formed from the mineral lazurite.[3]

The main component of lapis lazuli is lazurite (25% to 40%), a feldspathoid silicate mineral with the formula (Na,Ca)8(AlSiO4)6(S,SO4,Cl)1-2.[4] 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.
