Over 4000 years ago, a Chinese man was hungry so he decided to open some shells and feed himself. He became the first man to ever find a pearl!
In the past, pearls could be found in many parts of the world. Today, they are mostly in Bahrain and there are some reports of natural pearls from the Australian Indian Ocean.
Pearls are made of calcium carbonate and cochiolin. It is considered that a foreign body in the shell eventually becomes the pearl. For example, if a grain of sand enters the shell, the mollusk, irritated by the intruder, starts to coat the irritation with calcium carbonate and conchiolin. Eventually, that grain of sand will become the pearl.
When nature does everything by itself a pearl can be shaped perfectly round. There are eight basic shapes. They can be round, semi-round, button, tear, pear, baroque and circled. Of course, the perfectly rounded are very rare and due to this, the most expensive. Man has found a way to produce pearls, but they are never as beautiful as those from the wild.
In Japan they found a way to produce perfect pearls. It is almost like surgical intervention. They inject something in an oyster's body while at the same time they have to be so careful not to harm the oyster.
The largest ever was 5 centimetres long, with a circumference of 10 centimeters. They can be valuable if found in the wild, but because they are very rare the majority of pearls are cultivated or farmed (made from pearl oysters). Pearls from the sea are more expensive than those from freshwater. Of course, there are fake ones too that are not very expensive at all.
During the development of cultured pearl oysters, some species start to make pearls in colour (they can be pink, ream, silk or gold) However, the most interesting is the black pearl. The oysters that produce these are from the species Pinctada margaritifera. They are called "black Tahitian pearls", since they are farmed in Tahiti.
In the past, pearl hunting was the only way to harvest pearls. Divers would dive the ocean bottom or river bed and collect them. They had to check each pearl individually, because not every oyster has a pearl in it. In fact, from three tons of pearls, only three or four will have pearls.
Today Japan is the leading centre for producing pearls. Pearl dealers and wholesalers use Japanese weight measures called momme, and it is pronounced as 'moh-may' (1 momme equals 3.75 grams). Read more about pearls and their formation at http://www.butwhy.com.au/how-do-oysters-make-pearls
