10.8" Beam Calcite Crystal Cluster with Phantoms - Morocco

This is a beautiful, honey colored beam calcite crystal cluster that's part of a new find from the Atlas Mountains of Morocco. It features a bed of sharp calcite crystals that contain phantoms. They also contain sparkling inclusions that gathered at the terminations of the crystals near the conclusion of their formation.

The entire specimen measures 10.8" by 6.7" and has a flat base that allows for aesthetic presentation of the plate without the need for a display stand.

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.
