Formation & geological history

Discovered in 2019 in Pakistan, it is a combination of blue calcite and brown/white aragonite formed through sedimentary processes in karst environments or hydrothermal veins.

Uses & applications

Primarily used for lapidary purposes such as beads, spheres, carvings, and as a popular specimen for crystal healing and metaphysical collectors.

Geological facts

Despite its name, it is not from the Caribbean; it is named for its visual resemblance to tropical waters. It is a relatively new find on the mineral market.

Field identification & locations

Identify by its distinctive pastel blue-green color mixed with bands or pockets of sandy-brown aragonite. It is mostly found in the Balochistan province of Pakistan.
