Lapis lazuli is considered a rock that combines various minerals, mostly lazurite, but also contains calcite (white), sodalite (blue) and pyrite (fools' gold, a metallic yellow). A strong blue, sometimes with a hint of violet, lapis lazuil often has the presence of white patches (calcite) and sometimes small veins of pyrite. The Egyptians used lapis for seals, ground it for an eyelid cosmetic and often carved it into vases and figurines.
