Several people worked on figuring out to start a pearl growing, but Mikimoto is often the man credited with carrying the process to full development. It's similar to taking a plant cutting. Has your mother ever visited a friend's garden who shared a "slip" of geranium with her so she could start her own plant?
Well, in a similar way, to get a cultured pearl started, the mollusk needs a piece of mantle tissue from another mollusk.
A tiny piece of mantle tissue from a mussel or oyster is inserted into a live mollusk which is set back into a body of water. A "pearl sac" is developed around the piece and the mollusk begans coating the tissue with layers of nacre....the substance of pearls....making a pearl.
Often, for both sea and freshwater pearls, along with the tissue is placed a shell bead which can be a variety of shapes. The mollusk then coats this bead with pearl substance. This way, the shape of pearl can be controlled.
Those big beautiful round lustrous pearls that have always been popular are often mostly a shell bead inside with a coating of pearl on the outside. Are they real pearls? Yes! But be sure to buy from a reputable seller to make sure the coating is thick enough not to peel or wear off.
An akoya pearl, by the way, is a pearl from the akoya oyster (Pinctada Fucata Martensii), which lives in salt water.
