Pearls are the result of a natural process that has been used in jewelry since ancient times. It is made up of successive layers of mother-of-pearl shells, which give it this lustrous, multi-colored quality. Freshwater pearls are known for their abundance inducing a lower price. But, the gradual improvement of the techniques used for their culture makes it difficult today to distinguish a beautiful freshwater pearl from an Akoya pearl or a natural pearl.
