A Pearl is a hard mineral (CaCO ), typically spherical and is formed within the shell of an oyster or other bivalve mollusc. It is composed of calcium carbonate which is deposited in layers in a minute crystalline form.
As Pearls are made primarily of calcium carbonate, they can be easily dissolved in vinegar. Calcium carbonate is susceptible to even a weak acid solution because the crystals of calcium carbonate react with the acetic acid in the vinegar to form calcium acetate and carbon dioxide.
Great care must be taken when wearing Pearl necklace, especially Pearls in rings and bracelets. Also take care when applying perfume whilst wearing pearls.
Typically an ideal pearl is perfectly round in shape and smooth, but there are many other shapes that occur. Pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, the Pearl has become a metaphor for something rare, fine and valuable.

Pearls of great value occur spontaneously and naturally in the wild, and are extremely rare. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those currently sold on today’s market. Imitation pearls are also very commonly sold in inexpensive jewellery.
Pearls have been farmed and harvested not only for use in jewellery, but also used in medicines, paint formulations and cosmetics.
The unique lustre a pearls depends upon the reflection, refraction, and diffraction of light from the translucent layers. The thinner and more numerous the layers in the Pearl the finer the lustre. Pearls (most commonly cultured freshwater pearls) can be dyed yellow, green, blue, brown, pink, purple, or black.
Pearls - both natural and cultured are formed when a type of mollusc produces layers of nacre around some type of irritant inside its shell. With natural pearls, the irritant may even be another organism.
In cultured or ‘farmed’ Pearls apiece (or bead) of mother-of-pearl or a piece of tissue is inserted (by man) into the mollusc. For both natural and cultured pearls, the quality of the nacre dictates the quality of the lustre, which is very important to its beauty, demand and therefore its value. The surface of the pearl should generally be smooth and free of marks, while the overall shape could be round, oval, pear-shaped, or even misshapen. The misshapen pearls are called baroque pearls.
Cultured pearls are grown in farms. When the molluscs are old enough to accept the mother-of-pearl bead nucleus, the pearl technician (through avery delicate surgical procedure) implants the bead and then mollusc.
