The mantle is an organ that produces the oyster's shell, using minerals from the oyster's food. The material created by the mantle is called nacre. Nacre lines the inside of the shell. It's kind of like the oyster getting a splinter. The oyster's natural reaction is to cover up that irritant to protect itself.

This eventually forms a pearl. So a pearl is a foreign substance covered with layers of nacre. Most pearls that we see in jewelry stores are nicely rounded objects, which are the most valuable ones. Not all pearls turn out so well. Some pearls form in an uneven shape -- these are called baroque pearls. Pearls, as you've probably noticed, come in a variety of various colors, including white, black, gray, red, blue and green.

Most pearls can be found all over the world, but black pearls are indigenous to the South Pacific. Cultured pearls are created by the same process as natural pearls, but are given a slight nudge by pearl harvesters.

To create a cultured pearl, the harvester opens the oyster shell and cuts a small slit in the mantle tissue. Small irritants are then inserted under the mantle. In freshwater cultured pearls, cutting the mantle is enough to induce the nacre secretion that produces a pearl -- an irritant doesn't have to be inserted. So, the real question is, how are pearls made? In order to understand how oysters make pearls, you must understand an oyster's body composition. Oysters, which are a type of mollusk, have two shells.

Each shell features a protective layer that covers the mollusk's organs. This protective layer is called the mantle, and it is responsible for safeguarding vital organs that keep the mollusk alive. Although pearl clams and mussels exist, they are incredibly rare. N early all high-quality pearls come from oysters.

The Birth of a Pearl Oysters make pearls in response to an irritant, such as a grain of sand or another object. When any irritant makes its way between the mollusk's shell and mantle, the creature produces nacre, a protective coating that helps reduce irritation.

Nacre is also referred to as mother-of-pearl; it's made of microscopic crystals of calcium carbonate, and it also lines the interior of a mollusk's shell. Layers of nacre coat the irritant, eventually forming an iridescent gem the pearl.
