COMMENTS: The gem known as lapis lazuli, or simply lapis, is actually a rock, composed of lazurite, hauyne. sodalite, and nosean, all members of the sodalite group of minerals. Lazurite itself may be considered a sulfurrich hauyne. Calcite and pyrite in various percentages are also present in the rock. The finest lapis is considered to be a solid, deep blue with no white calcite spots and just a sprinkling of brassy yellow pyrite. Such material is found only in Afghanistan and Pakistan, in commercially interesting quantities. The Colorado material is quite fine but of limited availability
