Physical properties

Formation & geological history

Formed through sedimentary processes where calcium-rich fluids precipitate into cavities. These specific specimens are typically found in Pakistan and are geologically young, likely formed in the Holocene epoch.

Uses & applications

Primarily used for decorative purposes, ornamental carvings, lapidary art, and popular in the metaphysical and gemstone collecting communities.

Geological facts

Caribbean Calcite was only recently discovered in Pakistan in 2019. It is a unique combination of blue calcite and white/brown aragonite, giving it an appearance similar to a beach coastline.

Field identification & locations

Identify by its distinctive blue-green color paired with white druzy or brown sandy-looking aragonite layers. It is much softer than quartz. Most specimens on the market originate from the Balochistan region of Pakistan.
