Pearl is a beautiful creation of nature. Women have a passion for pearls and they fulfill their desire to look alluring and dazzling. Pearls are a symbol of purity and are gems found on the earth, and have a natural and lustrous appeal.
A pearl is a smooth and lustrous round structure formed naturally inside the shell of an oyster or a clam and is a most valued and precious jewel. It is formed when an irritant such as a grain of sand or tiny fish gets trapped in the internal tissues of a mollusks shell. To protect itself from this irritant, the mollusk releases nacre, a substance that sticks to the irritant and then forms a hard and smooth layer around the irritant. Nacre is released over time and forms layer after layer, which forms into a pearl.
Taking this as a cue, man started cultivating pearls manually. These are called cultured pearls. They are formed in a similar way, except the irritant is introduced into the mollusk by man and then the rest of the process of releasing nacre is natural. Most of the pearls that come into the market are cultured pearls these days and are no different than natural pearls. They are much cheaper than natural pearls...
