Freshwater pearls have been grown in pearl mussels that naturally live in freshwater. Pearls come in many shapes and sizes – rice, round, potato, button and stick are just a few. In nature, pearls come in a range of colors from white, cream or pale pink to natural tints of yellow, green, blue and black. The darker colors are more rare. Using an electroplating process, freshwater pearls can be treated to create gorgeous fashion colors – fuchsia, purple, blue, yellow and green. Unlike dyeing, electroplating results in a permanent color on the pearl.
