Almost all freshwater pearls in the world wide market today are fresh water culture pearls from China. They are generally less expensive than similar sized Cultured pearls that are grown in Saltwater, but not always. There are effectively no natural pearls on the market, and there have not been many on the world wide market for at least the last 100 years.

While white, and more recently black, saltwater pearls are by far the most popular, other color tints can be found on pearls from the oceans. Pink, blue, champagne, green, black and even purple saltwater pearls can be encountered, but to collect enough of these rare colors to form a complete string of the same size and same shade can take years.
There are freshwater pearls and saltwater pearls. Natural 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: see the freshwater pearl mussel. 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. Look here for more info: http://www.pinnaclepearls.com
