All pearls used on this site are Freshwater. I will make cultured Pearl pieces upon special request. As you will see, pearls come in many colors. Most pearls are bleached to lighten uneven dark areas that may appear under the nacre. This is permanent, provides a more uniform appearance and prepares the pearl for steps that can enhance the color. Because pearls are porous, they often absorb human oils, makeup and perfume, which can stain. In fact, pearls are soft, porous and accepting to all contact with natural and chemical substances, such as dyes. Pearl treaters take advantage of this porosity to achieve finer, more uniform colors with natural extracts and inorganic and/or chemical dyes. Dyes however, can fade over time. It’s a price that you pay for a very affordable product.
