Information About Pearl

 

Pearl is one of the most famous gemstones in different parts of the world, and it is of multiple sizes and colors, including:

 blue, yellow, green, and black. Pearls are distinguished by their luster and luster caused by the refraction of light in them. You make unique and sparkling jewelery with a high price tag, and in this article we will discuss more details about pearls, their formation and cultivation. 

 

§  Pearl-producing organisms

 

Pearl production is not limited to oysters only, as many people believe, there are other marine creatures that can produce pearls as well, such as: mussels and clams, and they all participate in being mollusks, but the largest proportion of pearls produced come from shellfish, and are considered The countries of Japan, China, Australia, and Tahiti are among the major countries producing and exporting pearls worldwide. 

 

§  How pearls are formed

 

 The process of pearl formation begins with the entry of a grain of sand, or any foreign body into the hollow of the shellfish, so the shellfish is considered that this body represents a threat to it, and to protect itself from it it secretes a substance known as mother of pearl, a substance that consists of organic and inorganic materials, Layers of mother-of-pearl accumulate on the foreign body inside the shell, and the result is the formation of a grain of pearl. It is indicated that this process does not occur in a short period, as it may take years to complete completely.

 

§  Pearl components

 

 Pearls are made up of 5% water, 5% from organic matter, and the largest percentage of pearls are calcium carbonate, which accounts for 90% of them.

                                         

                                                      

§  Pearl cultivation

 

Pearl production for several centuries depended on shellfish hunting, opening and killing, and then the Japanese scientist "Mikomoto" discovered a method of pearl cultivation, where pearl cultivation can be made in salt or fresh water as follows:

 

·      cultivation in fresh water 

 

begins this process of gathering farmers for mollusks as mussels They give them great attention and care until they get used to their new environment, then they mobilize them to be able to produce pearls, put them under observation and control, and they release mussels to water again in preparation for the process of creating pearls, and mussels need time to produce pearls ranging from a few months to Two years, depending on the type of mussels used, and in the last stage they extract the pearls, then they clean and polish them, then they offer them for sale to jewelry factories to form them in preparation for sale. 

 

·       Cultivation in brackish water

 

 In this type of cultivation, the same first steps as for freshwater cultivation are adopted, but after the shell has been alerted, farmers put small-sized mussels in small cages, then on private farms while they grow up, but the larger ones are lowered by Ropes to the depths of sea water for a period ranging from two to three years.
