Pearl

This page is currently not sponsored. Click here to sponsor this page.





A pearl is an organic mineral mixture formed with the soft living tissue of a shelled mollusk. Chemically pearls are made of calcium carbonate, either the mineral aragonite or a mixture of aragonite and calcite, sometimes also with minor vaterite.

Pearls are used as gemstones, but are not regarded as true minerals due to their organic origin.
