7" Realistic, Polished, Banded Orange Calcite Skull - Fluorescent!

This is a piece of banded orange calcite that has been meticulously polished into the shape of a skull. The calcite is a vibrant orange color and the banding alternates between orange and white calcite formations. The underside of the skull and the nostrils have been hollowed-out, making the specimen closer in resemblance to a real skull. This is a truly exceptional and beautiful crystal skull!

Under long wave UV, this calcite fluoresces in alternating bands of yellow-green and white.

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.
