How pearls are extracted

Pearls are a kind of gemstone, beautiful in appearance but expensive, and are characterized by its many colors of cream, gold, black, red, white, yellow and blue. Pearls are abundant in the form of a pear, while the ideal shape of the pearl is the circular shape, and it is available in several sizes, and pearls are a solid body produced slightly from mussels as well as clams, but is formed more in the oyster between the shell and the mollusk, whether it lives in water Fresh or salty, oysters can produce only one pearl. Pearls form natural pearls in the shellfish body, as a natural reaction to the entry of a parasitic body or a sand atom into the shell, and specifically between the shell and the soft body (Prince), and this intruder causes pain and itching of the oysters, and overcome the cells of the Prince to secrete material damage this intruder, and this begins This process can take a number of years. Pearls generally consist of 90% sodium carbonate, 5% organic matter, and 5% water. It should be noted that there is no difference between natural pearls and cultured pearls, both of which are produced from oysters naturally. Pearl extraction Pearls are extracted in two ways: catching oysters from the sea in large numbers, then killing all of them, and then extracted pearls.

Pearl culture, which was discovered by the Japanese scientist Mikimoto. How to grow oysters Cultivation of pearls in freshwater, and be by placing large numbers of bivalves in freshwater and attention and care, so get used to the new living environment, then conduct a simple and easy operation of the oysters, in order to alert him, to produce pearls, then put oysters in Intensive care, to observe any changes that occur, and then back to the water to form pearls, and the production of pearls depends largely on the quality and strength of oysters, there are oysters need several months, and another needs two years and so, after the formation of the pearl is extracted from the oysters, and the pearl is subjected to operations Cleaning and polishing to pour H ready for display on jewelry shops to sell. Cultivation of pearls in saltwater, this method does not differ from the steps of culturing

pearls in freshwater, but after the mobilization of oysters are placed largely in the depths of saltwater and leaves from two to three years, and it should be noted that the step of landing oysters to the sea is by rope. Saltwater pearls are usually more expensive than freshwater pearls, which are more commonly used in jewelry making, and are often made up of shell components. The problems of pearl cultivation are the death of mussels, due to the adverse weather changes of oysters such as heavy rains. The production of poor pearls by industrial waste, or even the death of oysters.
