Pristine, 2.7" Orange, Calcite Crystals - Bern, Switzerland

This is a beautiful 2.7" tall, red-orange calcite crystal cluster collected from Switzerland. The various layers of calcite phantoms can be seen when viewing the crystal with proper lighting.

Calcite, CaCO3, is a carbonate mineral and the most stable polymorph of calcium carbonate. The other polymorphs are the minerals aragonite and vaterite. Calcite crystals are trigonal-rhombohedral, though actual calcite rhombohedra are rare as natural crystals. However, they show a remarkable variety of habits including acute to obtuse rhombohedra, tabular forms, and prisms. Calcite exhibits several twinning types adding to the variety of observed forms. It may occur as fibrous, granular, lamellar, or compact. Cleavage is usually in three directions parallel to the rhombohedron form.
