1.7" Highly Fluorescent Scalenohedral Calcite Crystal - Wenshan Mine

This is an beautiful, colorless-yellow, scalenohedral calcite crystal. It is part of a new find at the Wenshan zinc mines in the Yunnan Province of China. Under short-wave ultraviolet light, the calcite exhibit a stunning white fluorescence.

It has been mounted to an acrylic display base with mineral tack.

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.
