Pearl is a gemstone that is formed within the soft tissue of a living shelled mollusk, such as an oyster or mussel. It is composed of calcium carbonate in the form of aragonite or a mixture of aragonite and calcite. Pearls are renowned for their lustrous appearance and have been highly valued as gemstones for centuries.
Natural pearls are formed when an irritant, such as a grain of sand or a parasite, enters the mollusk’s body. In response, the mollusk secretes layers of nacre, a combination of calcium carbonate and conchiolin, to coat the irritant and form a pearl. This process can take several years.

Natural pearls are formed when an irritant, such as a grain of sand or a parasite, enters the mollusk’s body. In response, the mollusk secretes layers of nacre, a combination of calcium carbonate and conchiolin, to coat the irritant and form a pearl. This process can take several years.
In addition to natural pearls, there are also cultured pearls. Cultured pearls are created through a similar process, but with the introduction of a foreign object by humans. This helps to stimulate the pearl-forming process in a controlled environment.
Pearls come in various shapes, sizes, and colors. They can be round, oval, teardrop-shaped (known as pear-shaped), or irregular. The most sought-after pearls are typically round and have a smooth surface with a high luster. The color of pearls can range from white, cream, and pink to black, gray, and even vibrant hues like blue and green.
