Physical properties

Mohs hardness of 3-4, glossy porcelain luster, ornate brown and black spots on a cream background, orthorhombic calcium carbonate crystal structure.

Formation & geological history

Formed through the biomineralization of marine mollusk shells accumulated in shallow tropical marine sedimentary environments over thousands to millions of years.

Uses & applications

Used primarily in fossil collecting, decorative display, and historical indigenous jewelry or currency.

Geological facts

Cowries were historically used as a form of currency across parts of Africa and Asia. Fossilized specimens preserve ancient marine ecosystems.

Field identification & locations

Identified by its smooth, oval shape, distinctive dorsal slit opening, and remaining natural spotted pattern. Found globally in coastal sedimentary deposits and fossil reefs.
