Blue calcite

Blue calcite, illustrated here as polished stones, is a variation of calcite characterized by its pale to deep blue hue. This mineral, a calcium carbonate, is known for its simple chemical composition but wide geographical distribution. The most notable deposits are found in Africa, North America, and Europe. Historically, calcite has been used in various cultures for decoration and architecture. Its formation usually occurs in sedimentary deposit contexts and sometimes in metamorphic zones. This calcite shows a smooth finish that highlights its chromatic softness and partial transparency.
