What is the difference between freshwater and South Sea Pearls?

Both varieties are cultured pearls, grown in an oyster shell with a little help from mankind. Freshwater pearls are relatively cheap to produce in shallow water and don't grow to the size or obtain the lustre of the South Sea Pearls.

South Sea Pearls are notoriously difficult to produce, because the oysters which produce them are found in the deep pristine waters of Northern Australia, often troubled by cyclones and tsunamis.
