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:
“Or else I thought her supernatural;
As though a sterner eye looked through her eye
On this foul world in its decline and fall,
On gangling stocks grown great, great stocks run dry,
Ancestral pearls all pitched into a sty,
Heroic reverie mocked by clown and knave....”
—William Butler Yeats (1865–1939)
