Often natural pearls and cultured pearls come to mind when looking for cultured pearl necklace. Both natural and cultured pearls are identical when it comes to formation of pearls. Both type of pearls are comprised of nacre layers. Natural pearls are formed when a small foreign object, such as a parasite or a grain of sand enters in the gonad or mantle tissue of a mollusk or oyster. In case of cultured pearls this mantle tissue is implanted surgically. After that process of formation of pearls is the same. In a defensive response to the irritant, the mollusk secretes nacre as a smooth, protective coating around the irritant and with multiple concentric layers of nacre, eventually pearl is formed.
The principle difference between natural pearls and cultured pearls is the thickness of nacre. Premature harvesting leads to thinner nacre and pearl farms constantly try to get the best quality cultured pearls every harvesting season.
