Cultured pearl or freshwater pearl? A freshwater pearl is a pearl that is cultured in a mussel in a lake, whereas the traditional cultured pearl is cultured in an oyster in the ocean (salt water pearls are called Akoya pearls). Freshwater cultured pearls are less expensive than the Akoya pearls. Freshwater pearls come in many shapes from round to button shapes, from flat flakes to rice shapes and in many colors. As with the salt water Akoya pearl, the round shapes are generally more expensive.
