6.1" Dogtooth Calcite Crystal Cluster - Morocco

This is a beautiful, yellow-beige colored beam calcite crystal cluster that's part of a new find from the Atlas Mountains of Morocco. The calcite crystals contain phantoms that were created by a small unidentified dark mineral.

The entire specimen measures 6.1" by 4.1" and it comes with an acrylic 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.
