Why are there knots between pearls in the strand of a necklace?
There are two major reasons why. First, it is to protect the pearls from coming into contact to one another which will cause unnecessary wear and tear. Secondly, it prevents your entire strand of pearls from scattering all over the floor when the unfortunate happens. When your necklace is knotted, only one pearl will roll down and it can be easily retrieve.
