Others Tips of Black Pearls
After wear them, just wipe them off with a soft cloth or chamois which can be dry or damp. This will prevent the dirt from accumulating and keep perspiration, which is slightly acidic, from eating away at the pearl nacre.
Take black pearls off when showering or swimming, which get string wet, and chlorine or soap damage the black pearls.
When you take off a black pearl ring, grasp the shank or metal part rather than the pearl, prevent them from loosening and coming into contact with skin oil on your hand.
Avoid wearing pearls with rough fabrics such as Shetland wool, which scratch the pearls.
