9" Golden, "Beam Calcite" Crystal Cluster - Morocco

 
 
This is a beautiful, honey colored beam calcite crystal cluster that's part of a new find from the Atlas Mountains of Morocco. Some of the crystals at the top of the specimen are twinned and have golden-yellow coloration. They sit atop a bed of sharp calcite crystals that contain phantoms. They also contain sparkling inclusions that gathered at the tops of the crystals near the conclusion of their formation.

Some of the superior most crystals have undergone some damage, this has been reflected in the price of the specimen. The entire specimen measures 9" by 7.8" 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.
