7.7" Yellow Calcite On Scolecite (Zeolite) Sprays - Maharashtra, India

This is a fantastic cabinet specimen from the Deccan Traps of India. It features round yellow calcite crystals perched atop sprays of white scolecite crystals. It stands up nicely on one edge or sitting flat without the need for a display stand, however an acrylic/metal display stand will accompany this specimen for preferred presentation.

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.
