Pearls have been a symbol of class, beauty and sophistication.
Freshwater pearls come from oysters that mature in non-saline water (from lakes or ponds, as opposed to saltwater from the sea). Freshwater pearls usually are not as round as saltwater pearls.
Tahitian Black pearls come from the black-lipped oyster, in the islands of French Polynesia. The pearls are unique because of their natural dark colors.
