I have (I think) a strand of 9mm natural pearls. The pearls are pealing. I am not sure why, but it could be from perfume or other cosmetics. I have attached a picture showing the damage. Each pearl is showing some damage. I have heard that it may be possible to repair the pearls, as they are a nice color and size. My question, does anyone know about this process and/or of someone who can do this?
