This article contains basic information about the cultivation of pearls in fresh water which is useful for newer people interested in farming or business of pearls. In fact, pearl farming is a difficult business in water, especially if you are going to start now. The biggest advantage in pearl farming is that it gets high prices in its market. In addition, its finished goods are light weighted and are not destroyed. If the matter of grafting is to be abandoned, pearl farming or business is relatively easy fishery business, in which artificial seeds are not needed (especially as it happens in marine crops).

Pearls are considered as natural gems or jewels and which are produced from oyster. Pearl is one of the most beautiful gems available to us, and it is a very beautiful because of which it is so famous all over the world. These pearls are sold at good prices in the market.

So, Where do these pearls come from?

On the one hand, where natural pearls are found in marine organisms, on the other hand, the formation of artificial or cultured pearls occurs when surgery is performed in the mammal (a type of cowries), making the nucleus, which starts the process of forming pearls.

When it comes to the formation of pearls, usually any shelled oyster can produce pearls, but in the oyster in which there are pearl lines or shell, i.e.  the shell can cause shiny pearls on the surface of the inner chamber.

 Here the question arises, how are these pearls made?

There are basically 3 types of pearls that are available : Natural, cultured and imitation.

Natural Pearls form when an irritant - usually a parasite and not the proverbial grain of sand - works its way into an oyster, mussel, or clam. As a defense mechanism, a fluid is used to coat the irritant. Layer upon layer of this coating, called 'nacre', is deposited until a lustrous pearl is formed.

A cultured pearl undergoes the same process. The only difference is that the irritant is a surgically implanted bead or piece of shell called Mother of Pearl. These 'seeds' or 'nuclei' are most often formed from mussel shells. Quality cultured pearls require a sufficient amount of time - generally at least 3 years - for a thick layer of nacre to be deposited, resulting in a beautiful, gem-quality pearl. Lower-quality pearls have often been 'rushed' out of the oyster too quickly (sometimes a year or less) and have a too-thin coat of nacre. 

Pearls can come from either salt or freshwater sources. Historically, saltwater pearls were rounder and had a better nacre than freshwater pearls, while freshwater pearls tended to be very irregular in shape, with a puffed rice appearance the most prevalent. However, improvements in freshwater pearl farming techniques have narrowed that gap, with freshwater pearls now exhibiting great roundness and deep luster.

The culturing process usually takes several years. Mussels must reach a mature age, which can take up to 3 years, and only then can be implanted or naturally receive an irritant. Once the irritant is in place, it can take up to another 3 years for the pearl to reach its full size and nacre thickness.  Of the pearls produced, only approximately 5% are of sufficient true gem-quality for top jewelry makers, yet a pearl farmer can figure on spending over $100 for every oyster that is farmed, whether a gem-quality pearl is produced or not.

Imitation pearls are a different story altogether. In most cases, a glass bead is dipped into a solution made from fish scales. This coating is thin and may eventually wear off. One can usually tell an imitation by rubbing it across the teeth: Fake pearls glide across your teeth, while the layers of nacre on real pearls feel gritty. The Island of Mallorca is known for its imitation pearl industry, and the term "Mallorca Pearls" or "Majorica Pearls" is frequently (though inaccurately) used to describe these pearl simulants.

 And, How much time does it take to produce pearls?

So the answer is that it depends on the type of pearl and the formation of pearls, which may take several months to several years. In the production of pearls, natural pearls, pearls born in seawater and pearls born in fresh water are included.

Pearl Producing Countries :

Countries like China, Japan, Australia, South Sea, Vietnam, India, UAE, USA, Mexico, Fiji, Philippines, France, Myanmar and Indonesia are the major pearl producing nations.

In our next article, We will discuss of this farming, its method and how to proceed with this. And Next we will discuss about the 'pearl born in fresh water'.
