What is Pearl?
A pearl is a hard, roundish object produced within the soft tissue (specifically the mantle) of a living shelled mollusk. Just like the shell of mollusks, a pearl is composed of calcium carbonate in minute crystalline form, which has been deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes of pearls (baroque pearls) occur.
The finest quality natural pearls have been highly valued as gemstones and objects of beauty for many centuries, and because of this, the word pearl became a metaphor for something very rare, very fine, very admirable and very valuable.
Natural pearls are nearly 100% calcium carbonate and conchiolin. It is thought that natural pearls form under a set of accidental conditions when a microscopic intruder or parasite enters a bivalve mollusk, and settles inside the shell. The mollusk, being irritated by the intruder, secretes the calcium carbonate and conchiolin to cover the irritant. This secretion process is repeated many times, thus producing a pearl. Natural pearls come in many shapes, with perfectly round ones being comparatively rare.
Cultured pearls (nucleated and non-nucleated or tissue nucleated cultured pearls) and imitation pearls can be distinguished from natural pearls by X-ray examination. Nucleated cultured pearls are often 'pre-formed' as they tend to follow the shape of the implanted shell bead nucleus. Once the pre-formed beads are inserted into the oyster, it secretes a few layers of nacre around the outside surface of the implant before it is removed after six months or more.
When a nucleated cultured pearl is X-rayed, it reveals a different structure to that of a natural pearl. A cultured pearl shows a solid center with no concentric growth rings, whereas a natural pearl shows a series of concentric growth rings.

About Pearl Gemstone:
The name denotes a calcareous concretion with a silvery lustre formed within the shell of certain bivalve molluscs known as pearl oysters around some foreign body. There are two types: natural pearls, formed inside wild oysters, practically impossible to find nowadays, and cultured pearls in which the production of the pearl is artificially induced. Natural pearls have no nucleus, but in the cultured variety the pearl is formed round a spherical bead inserted into the oyster shell. The oyster tries to render this intrusive body innocuous by sealing it off in a cyst of nacre.
Both natural and cultured pearls are a sound investment as their price is never likely to come down; quite the contrary, it continues to rise inexorably.
The finest natural pearls are fished almost exclusively from the Persian Gulf and the China Sea, while the best cultivated ones come from Japan, Korea and more recently Australia.
The price of a pearl depends much on its provenance, colour and iridescent lustre (known as the "orient") perfect shape and above all size. In fact, the most important characteristic in computing the value of a round pearl is its diameter, which should exceed 8mm.
The finest colours are pinkish-white, bluish-white and white- white. Avoid pearls of a yellowish, greenish or brownish tint. Grey, blue and black pearls are to be found in certain volcanic regions such as Tahiti and may be even more expensive that the white variety.
Pearls may also be of different shapes: round, oval, button and drop (often used for earrings) or of an uneven form, which are known as "baroque" pearls.
Pearl is a rare and living substance and should be treated with great care. If you live in a hot climate, your pearls should be washed in sea water at least twice a year; in cooler climates, once is sufficient. They should not be brought into contact with perfume or other jewelry, which might scratch them.
