Freshwater and Saltwater Pearls
Freshwater and saltwater pearls may sometimes look quite similar, but they come from different sources.
Freshwater pearls form in various species of freshwater mussels, family Unionidae, which live in lakes, rivers, ponds and other bodies of fresh water. These freshwater pearl mussels occur not only in hotter climates, but also in colder more temperate areas such as Scotland (where they are totally protected under law). However, most freshwater cultured pearls sold today come from China.
Saltwater pearls grow within pearl oysters, family Pteriidae, which live in oceans. Saltwater pearl oysters are usually cultivated in protected lagoons or volcanic atolls.

Famous quotes containing the word pearls:
“Love’s secrets, being mysteries, ever pertain to the transcendent and the infinite; and so they are as airy bridges, by which our further shadows pass over into the regions of the golden mists and exhalations; whence all poetical, lovely thoughts are engendered, and drop into us, as though pearls should drop from rainbows.”
—Herman Melville (1819–1891)
