Is the color on dyed pearls permanent?
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. These dyes can fade over time. But to stress the positive: matched strands are easier to create, and more affordable.
