What is Pearl
Pearl is an object that Bivalvia, like oysters, produce. When oysters get hurt in the internal part or something gets into their shell, they release a kind of calcium carbonate called nacre and cover the foreign object or wound with nacre layers, and the thing with nacre layers will then become Pearl. Pearls get special luster because nacre layers reflect and diffract the lights, and the color of Pearls may depends on what kind of Bivalvia it comes from; generally speaking, the more nacre layers Pearl has, the more beautiful it is. Pearls that are naturally produced are seldom in round shape, they are usually in various shapes. Except making jewelry, some eastern countries believe that Pearls have an effect of skin whitening so they grind Pearls into powder and take it as medicine.
History of Pearl
People could only got Pearls by searching under the sea formerly; in Chinese history, Dan-min was mentioned to be someone who gathered Pearls from the sea as a job, and sea women in Japan also did it as part of their job in early years. At that time, Pearls were hard to collect and only few of them can be found, people took Pearls as a sign of rich and powerful. During Song dynasty, China started to process Pearl cultivation and became the first country of this action. However, Kokichi Mikimoto from Japan cultivated Pearls on a large scale successfully during 1893, because of him, Japan became the first country of cultivated Pearls on a large scale. The brand that Mr. Mikimoto creates is still a famous jewelry company which has branch stores in Europe. Pearls are no longer for rich people only, they gradually turn into a kind of fashion, even so, Pearls may cost differently due to their place of origin, quality or type of Pearls.
Origin of Pearl
There are five main origin of pearls: China, Tahiti, Japan and Australia. Pearl from each place has features of their own.
- Zhuji city in Zhejiang province, China is the biggest origin of freshwater cultured Pearl that covers 75% of the world's production, because of the huge production, Zhuji city is known as the village of Pearl in China. The size of freshwater cultured Pearl is smaller and normally is oval or flat- round shape, and the price is also lower.
- Tahiti is famous for its black Pearl, which is the queen of Pearl. It was produced by the black lip oyster that lives in the clean sea area near Tahiti. Differ from other Pearls, it is grey or black color, and the most expensive Pearls are the ones with peacock green color. Since black lip oysters are sensitive to their living environment, the cost of producing black Pearls are higher than other Pearls, and of course the price of black Pearls are higher.
- Akoya Pearl is a kind of sea cultured Pearl, it is bigger and rounder than freshwater cultured Pearl. Akoya Pearl can be pink, silver white or milky color, and they are appreciated all over the world.
- Pearls produced by Australia are called south sea Pearls, Even though Indonesia and Philippines produce south sea Pearl as well, Australia is still the biggest origin. Since the size of the seashells that produce these Pearls are bigger than others, the size of the Pearls are usually bigger than other kinds of Pearls, and this becomes the feature of south sea Pearls. South sea Pearls can be found in different colors, they can be white, gold or other beautiful colors without dyeing them.
