Formation & geological history

Formed through sedimentary processes involving the precipitation of calcium carbonate in marine environments or caves. Most specimens currently on the market are found in Pakistan.

Uses & applications

Primarily used as a decorative stone for lapidary work, carvings, spheres, towers (points), and as a collector's specimen.

Geological facts

Despite the name 'Caribbean Calcite,' it is actually sourced from Pakistan; the name refers to its resemblance to tropical beach colors rather than its geographical origin.

Field identification & locations

Identify by its distinctive light blue color paired with white or brownish aragonite bands. It is soft and will effervesce (fizz) if in contact with weak acid.
