Pearls are formed inside the shells of certain mollusks, particularly oysters and mussels, as a defense mechanism against irritants such as sand or parasites that get inside their shells. When an irritant enters the mollusk's shell, the animal secretes nacre, a substance made of calcium carbonate and protein, to coat the irritant. Over time, layers of nacre build up around the irritant, forming a pearl.
Natural pearls are rare and valuable because they are formed by chance. Most pearls available in the market today are cultured pearls, meaning they are created intentionally by farmers who introduce an irritant, typically a small bead, into the mollusk's shell and then place it back in the water. The mollusk secretes nacre around the irritant, producing a pearl.
Cultured pearls are typically grown for about 2-3 years before they are harvested. The pearls are collected by opening the mollusk's shell and removing the pearl. After harvesting, the pearls are cleaned, sorted, and sometimes treated to enhance their color or luster.
The most valuable pearls are typically those produced by certain species of oysters, such as the Pinctada maxima and Pinctada margaritifera, which are found in the South Pacific, particularly in the waters around Tahiti and the Cook Islands. These oysters produce pearls with unique colors and luster, such as the famous black Tahitian pearls.
In summary, pearls are formed inside mollusks as a defense mechanism, and cultured pearls are created intentionally by introducing an irritant into the mollusk's shell. The most valuable pearls are typically produced by certain species of oysters found in the South Pacific.
