A spherical, spherical secretion formed within the shell of some molluscs and oysters and classified as precious stones.

It is an interlocking tissue between the shell and the body. It is arranged in successive layers around an annoying body. Usually, parasites in the case of natural pearls are attached to the fine shell of the oyster. The pearl is constructed from layers of argonite or calcite (crystalline crystalline carbonate). The layers are held together by a concoilin material, which is similar to that of the pearl, which forms the inner layer of the oyster shell.

Composition of Pearls:
Pearls may be in the shape of a grain of rice, spherical, pear shaped, shaped, or irregularly shaped and evaluated in this order. Pearls that are attached to the inner surface of the shell are known as "
The luster or unique brilliance of the pearls depends on the reflection and refraction of light from the semi-transparent layers, which are more accurate in proportion and the less dense and more numerous layers.
The best types of pearls are usually white in color, sometimes with an ivory or light pink touch, as well as a touch of yellow, green, blue, brown, and black. Black pearls are very expensive because of their scarcity.
The brilliance shown by some pearls due to overlapping layers that break the light falling on its surface.
The pearls are not cut or polished like other stones. They are very soft and are affected by acids and heat. As organic substances, they are susceptible to biodegradation.
Pearls are obtained from salty oysters (especially Pinctata) as well as freshwater oysters (especially Hyriopsis). The largest natural pearls center in the world is the Arabian Gulf, which is said to produce the best saltwater pearls. Other important sources include the coast of India China, Japan, Australia, the various Pacific islands, Venezuela, Central America, the rivers of Europe and North America. In ancient times, the Red Sea was an important source of pearl fishing.

Natural pearls:
The pearl can be defined as a solid substance made up of calcium carbonate and organic matter. It is formed by mollusks such as shellfish and mussel in response to an irritation caused by a foreign body. The body enters the cavity of the molluscs.
