Pearl Gemstone

Natural pearl stone is extremely rare to find these days. However, thanks to the modern science which has allowed a human being to sufficiently harvest cultured pearl gemstone which appears apparently like a natural pearl gemstone. Natural pearl stone or wild pearl stone is composed of entirely calcium carbonate.

The natural pearl stone is being created accidentally when a parasite intrudes inside the bivalve mollusk, consequently, by the presence of the parasite inside the mollusk. Eventually, it gets annoyed by the sudden attack of the intruder and structures the pearl sac external mantle tissue cells and hides the calcium carbonate to cover the irritant parasite.

This hiding process of calcium carbonate is repeated an innumerable number of times, and eventually; give birth to a natural pearl stone. Typically, this is the process of creating a natural pearl stone or wild pearl stone which has been produced without human intervention. Since ancient times, pearl hunter searches for wild pearl or natural pearl stone in different seashores.

Although, ever since from the inception of pearl stone due to its spell-bound beautiful men and women highly appreciate to adorn this gemstone in their clothes and jewelry. Nevertheless, the production of natural pearl stone or the wild pearl stone cannot meet up with the demands of users; therefore in order to appease the demand of user’s human being has invented a scientific way of producing pearl stone which look similar to natural pearl stone. Hence, it has been named cultured pearl stone. Now let’s see that how cultured pearl stones are formed.

Cultured Pearl Stone:

The cultured pearl stone are those stones which are produced or cultivated with human intervention or, in other words, it is impossible to harvest cultured pearl stone without human intervention. Usually, this stone is produced when a parasite (irritant) is intentionally implanted in the oyster of a shell of mussel.

Eventually, by implanting an irritant inside the mussel of shell, causing the mollusk of the shell to get irritated by the intruder parasite as a result pearl sac of external mantle tissue cells secretes the calcium carbonate and conchiolin to cover the irritant. Ultimately, due to the continuation of this process cultured pearl stone is produced which look similar to the natural pearl stone.

Formation of Cultured Pearl Stone:

After implanting irritant parasite in the oyster it is left in the water. During that period of being in water, due to fluctuations in temperatures and the environment around the oyster the external layer of pearl structures.

Ultimately, a sponge-like layer of conchiolin forms around the nacre. The nacre composed of thin layers of calcium carbonate which are called aragonite. Due to this layer when a cultured pearl stone is rubbed against teeth, it resembles the difference between real pearl stone and cultured pearl stone.

Harvesting:

The pearl stone is being harvested ideally during the time of winter. Since, during that period the pearl produce is better in color, luster, and shine. A cultured pearl stone takes around one to three years of time to be developed completely. Typically, the growth of the pearl is being invigilated by x-ray machine and while cutting the pearl stone from oyster flesh proper care has to be taken.

Mainly, cultured pearl stone is cultivated in freshwater, salt sea water, South sea water and black Tahitian.
