Cowries (esp. "Cypraea moneta") were used as a currency in Africa (Ghanaian cedi in Ghana named after cowry shells) and elsewhere, such as in China where the shell or copies of the shell were in theory used as a means of exchange. They are also worn as jewelry or otherwise used as ornaments or charms, as they are viewed as symbols of womanhood, fertility, birth and wealth. Many find the shiny, porcelain-like shells pleasing to look at.
