Notes
Sample weighs 34 kg. Lapis lazuli is not a mineral, but rather a metamorphic rock composed of multiple minerals. It acquires its blue color from lazurite, a blue silicate mineral of the sodalite group. In addition, specimens usually contain calcite and pyrite. Sodalite, hauyne, wollastonite, afghanite, mica, dolomite, diopside, and other minerals might also be present. To be called "lapis lazuli," a rock must have a distinctly blue color and contain at least 25% lazurite.
