Physical Properties

Hardness: 3 on Mohs scale; Color: Cream, tan, brown, and white banding; Luster: Vitreous to waxy; Crystal Structure: Trigonal/Hexagonal; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71

Formation & Geological History

Formed through the precipitation of calcium-rich waters in sedimentary environments, often in caves or hot springs as travertine or flowstone.

Uses & Applications

Primarily used as decorative display pieces (towers/points), lapidary art, and in the metaphysical community for collecting.

Geological Facts

While often marketed as 'Caribbean Calcite' if it contains blue hues, this specimen is a variety of aragonite/calcite transition. It is very soft and will react (fizz) if exposed to weak acids like vinegar.

Field Identification & Locations

Identify by its characteristic banding, waxy texture, and softness (it can be scratched by a copper penny or steel knife). Commonly sourced from Pakistan and Mexico.
