Banded Calcite (often sold as Caribbean Calcite or Pink Calcite)

Physical Properties

Hardness: 3 on Mohs scale (easily scratched by steel); Color: Pink to peach with distinctive cream/white banding; Luster: Vitreous to waxy; Crystal Structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral.

Formation & Geological History

Commonly formed in sedimentary environments, specifically through chemical precipitation in caves or hot springs. The banding represents different stages of mineral deposition over thousands of years.

Uses & Applications

Primarily used for decorative purposes, lapidary art, 'healing crystal' collections, and interior design. Due to its softness, it is not ideal for ring jewelry.

Geological Facts

While this specific cut is a modern polished point (tower), banded calcite has been used since ancient Egypt for carving Alabaster vases and sarcophagi.

Field Identification & Locations

Identify in the field by its low hardness and vigorous reaction (effervescence) when exposed to a drop of cold dilute hydrochloric acid. It is commonly found in Pakistan and Mexico.
