Formation Process Of A Pearl

By Sandra Sullivan


Many years ago, pearls have been known for its unique physical appearance, considering it as a very treasure that oysters and the seabed have kept. People use this as part of their jewelry and as a precious ornament. Before makers transform it into a Hawaiian Pearl Jewelry, the formation of such gem would take a procedure that could take years.

What comprises a pearl is an estimated of 100% conchiolin and calcium carbonate. People refer the way a natural type is made to be incidental. Because the process starts from a single microscopic parasite who wants to invade the shell.

Such parasite is named as the irritant. This irritant will make a way to invade any oyster that it sees. Once it is already inside the oyster will defensively response to the invader, creating a fluid that would cover and trap the invader. The coating consists of both calcium carbonate and conchiolin, which are essential in creating such a gem.

When the coating is continuously done, the product that is also known as the nacre will be formed. It will approximately take 3 years to create one pearl through this process. Different shapes can be created, but the rarest which is the perfectly round one is what is made to be a jewel.

Cultural pearls are formed in a somewhat the same process as what the natural one. This happens through implantation of a tissue, referred to as the graft, to a shell. A donation is done by another mollusk to another same kind, that causes a reaction. This reaction is when the recipient creates a sac that will coat the graft and will trigger to secrete calcium carbonate. Hence, a nacre will be the product.

There have been many methods used in producing a cultured one. It could either be using shells from freshwater or seawater, transplanting the tissue into the shell, or adding a round bead as a nucleus. Unlike the natural type, this is made both by human and also natural occurrences.

Another type of nacre can be easily created, this is called the imitation pearl. A round glass bead is created, and dipping it into a liquid mixture that is made up of fish scales. After dipping it, a fake one is created. The real nacre s heavy and these are not, also the coating is just thin.

You could differentiate a fake from a real pearl through rubbing it against your teeth. If the color wears away then it is fake. Fakes are done in a short period but the real one is made for a long period of time.

Forming a real single pearl could take years before divers get it and jewelry makers use it as part of the jewels they are making. Even in the long procedure, a beautiful thing will be put into existence. So if you have any of this special gem, take good care of it because it was made in an extraordinary way.
