Pearls have long been a symbol of purity, due to their gleaming natural beauty. The most highly valued pearls are created inside saltwater oysters and freshwater clams. Cultured pearls are essentially the same as those found in nature, the only difference being a foreign particle is inserted into the mollusc with the express purpose of creating a gemstone. For the romantically minded, the ancient Greeks held the belief that pearls were the tears of joy from Aphrodite, the goddess of love.
