Pearls are the only gems that are produced by an animal. Cultivators mimic the way natural, uncultured pearls are created by implanting a beadlike nucleus from a mollusk shell into an oyster, and the animal responds to the irritant by coating it with a pearlescent nacre of calcium carbonate, layer by layer, multiple times per day.
