What is a Pearl ?
Organic mineral formations known as pearls have long been prized as valuable gemstones. The bulk of commercial pearls are extracted from bivalves (two-shelled molluscs), which include marine oysters and freshwater mussels. They are produced by a variety of molluscs, including gastropods that resemble snails, such as abalones.
How natural pearls are formed ?
When an irritant enters a specific species of oyster, mussel, or clam, a natural pearl is created. The mollusk secretes a liquid to coat the irritant as a protection mechanism. This coating is applied on the irritant in successive layers until a gleaming pearl develops.
How cultured pearls are formed ?
The procedure is the same for cultured pearls. The sole distinction is that the irritant in this case is a Mother of Pearl bead or shell fragment that has been surgically placed. These shells are frequently pulverised oyster shells, which are highly valuable on their own as catalysts for high-quality pearls. As a result, the core is significantly larger than it would be in a genuine pearl. However, the size of the nucleus has little bearing on the appearance or robustness of the pearl as long as there are enough layers of nacre to produce a lovely, gem-quality pearl.
Pearls can be found in freshwater or saltwater. Although there are some varieties of freshwater pearls that are thought to be of good quality, saltwater pearls often tend to be of greater quality. Freshwater pearls typically have very erratic shapes, with the look of puffed rice being the most common. However, rather than the pearls origin, value is determined by each pearls distinct merits.
