They are irregular in shape but have good color and luster. A small square of mother of pearl in inserted into the clam. These pearls require three years to produce good results.<br /> <br /> <br /> KESHI PEARL<br /> <br /> <br /> Keshi pearls are a non-beaded pearl formed by accident as a by-product of a pearl culturing operation. Keshi may form in either saltwater or freshwater pearls. <br /> <br /> Keshi pearls vary in their shapes, come in a wide variety of colors, and tend to have high luster. <br /> <br /> <br /> Keshi pearls are formed when the oyster rejects and spits out the implanted nucleus before the culturing process is complete and forms separate pearl sacs without nuclei. These pearl sacs eventually produce pearls without a nucleus - the keshi pearl.<br /> <br /> <br /> <br />
