Physical properties

Formation & geological history

Formed through sedimentary processes involving the precipitation of calcium carbonate in marine environments. This specific variety was newly discovered in 2019 in Pakistan and is typically found in pockets of sedimentary rock.

Uses & applications

Primarily used as a decorative stone, for carving into spheres (as shown), towers, and palm stones. It is highly valued in the metaphysical and gemstone collecting communities.

Geological facts

Caribbean Calcite is actually a combination of blue calcite and light brown/white aragonite. Despite its name, it is not actually from the Caribbean; it is sourced exclusively from Pakistan and is considered a relatively new find in the mineral market.

Field identification & locations

Identify by its distinctive 'beach-like' appearance resembling turquoise waters and white sand. Collectors should look for the characteristic tiny crevices or 'vugs' common in this mineral. It is very soft and can be easily scratched by a steel knife.
