Lapis Lazuli tumble stones from Afghanistan
Lapis Lazuli
Lapis Lazuli is a deep blue rock composed mainly of the mineral lazurite, often accompanied by calcite and pyrite. The stone has been in use for jewellery, sculpture and pigment for thousands of years, and was particularly prized in ancient times for its intense colour. Small golden inclusions of pyrite give lapis lazuli a characteristic speckled appearance.
Lapis lazuli is mainly mined in Afghanistan, especially in Badakhshan province. Other deposits include Chile, Russia and Pakistan. The rock is formed by metamorphic processes in which limestone changes under high pressure and temperature. Its hardness is between 5 and 5.5 on the Mohs scale.
