Some pearls may have some “poor quality” layers, so their beauty attributes are diminished: they may have spots, welts and low luster; it is for this reason that some people have sought a way to "remove" these unwanted imperfections, with the hope that by removing some outer layers those in its interior are of better quality and the pearl will look beautiful. This process is called “Pearl Peeling”.
