Formation & geological history

Formed through regional metamorphism or hydrothermal alteration of basic igneous rocks or calcium-rich sedimentary rocks. It is often found in quartz veins and manganese-bearing rocks.

Uses & applications

Used primarily as a decorative stone, in jewelry (cabochons and beads), and as a carving material for ornamental objects. It is a popular collector's mineral.

Geological facts

First discovered in Sauland, Norway, in 1820 and named after the mythical island of Thule. It gets its distinctive pink color from trace amounts of manganese (Mn) replacing calcium in the crystal structure.

Field identification & locations

Identify by its unique 'bubblegum pink' color mottled with white calcite or quartz. Most commonly found in Norway, but also in Namibia, Australia, and parts of the United States like North Carolina and Washington.
