ferent from the common faith that pearls are perfectly round lustrous objects, not all pearls, are so well-formed.

It's too many momentous to understand the anatomy of oysters, and its body mechanisms to comprehend how oysters make pearls. The shell of the oyster contains two parts, which are connected at an springy ligament. The ligament helps beginning of the shell so namely the oyster can fared. As the oysters start to grow, its the shell increasing in size. This boost of the oyster shell is helped an organ known as the mantle. The mantle uses the some minerals in the oyster’s food to fashion this shell. The interior chapter of the shell namely lined at nacre, a matter created at the mantle. Sometimes while the shell opens, a curious substance manages to slip into the inside of the shell and then resides between the shell and the mantle. As a response to this, the oyster covers this foreign substance for a part of its self-defense mechanism. The same nacre that is accustom to manner the shell is used to cover this strange material by forming a lot of layers around it. This finally leads to formation of a small circular object which is known as pearl.
Cultured pearls are formed with some manual aid. The pearl peasant opens the oyester's shell, cuts a small cut in the mantle and put a small irritant, such as a sand. The oyster remedies it as a strange object and covers it with tons of layers of nacre to form a pearl. Oysters can make pearls in any type of water.
