Physical properties

Hardness: 3 on Mohs scale; Color: Pale blue, white, and light brown/tan; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71

Formation & geological history

Formed as a sedimentary mineral through chemical precipitation in marine environments or caves. This specific variety was recently discovered in Pakistan (around 2019) and likely formed during the Cenozoic era.

Uses & applications

Primarily used for decorative items such as spheres, towers, and carvings. Highly valued in the metaphysical community for meditation and as a collector's specimen due to its unique color palette.

Geological facts

Blue Caribbean Calcite is a relatively new discovery found only in Pakistan. It is actually a combination of light blue Calcite and brown/white Aragonite, often resembling a beach landscape from an aerial view.

Field identification & locations

To identify in the field, look for the 'beachy' banding of blue and tan. It is soft and will react (fizz) with dilute hydrochloric acid. It is currently only sourced from the Balochistan province of Pakistan.
