A pearl is a small, round object created by certain species of mollusks. The pearls are created overtime by the mollusk depositing layers of calcium carbonate over an irritating intrusion in its shell. Pearls have a tremendous variety of sizes, shapes, and luster as well as their origination location. These factors all play a role in determining the value of the gemstone.

Cultivating pearls began in Japan in the very late 1800s, and the process is now responsible for almost all pearls used in jewelry today. Cultivation includes implanting a small piece of polished abalone into a mussel along with an irritant to stimulate production. The pearl takes roughly three years to cultivate, and when it is removed, the mussel is often used again to create another pearl.
