1. Pearl formation is a natural process
It all starts with a simple oyster or mussel. When a strange object, such as a grain of sand or a small parasite, finds its way to the shell of one of these molluscs, the oyster responds in a unique way. To protect itself against the intruder, the oyster begins to separate layers of mother -of -pearl to cover the annoying object. These layers of mother -of -pearl ultimately form a beautiful pearl.
