Freshwater cultured Pearls are grown in fresh waters, as their name might suggest. They have many shapes: round, nearly-round and off-round. Freshwater pearls are the most affordable, offering the alternative choice of bigger pearls at a lower cost. They come in many colors such as white, pink, peach, peacock, and black. Presenting a very fashionable look, a freshwater pearl necklace is a perfect gift for a graduation or sweet 16.
