1.95" Calcite Crystal with Hematite Inclusions - Fluorescent!

This is a beautiful calcite crystal that contains hematite inclusions. This specimen was collected from Daye County in the Hubei Province of China. Under long wave UV, these crystals react by fluorescing orange.

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.
