The term "keshi pearl" was first coined by Japanese pearl harvesters to describe tiny, seed-sized pearls found inside wild Akoya oysters. These tiny pearls were referred to as keshi, which has the literal translation of poppy or poppy seed in Japanese and were considered to be basically useless because they were too small to be drilled. So the original definition for a keshi pearl was very concise: the tiny, too small to drill, truly natural pearl that is harvested from a wild Akoya oyster. During the 1920’s, Japanese pearl farmers started nucleating Akoya oysters to form cultured pearls. What they found was that many times, as a result of the nucleating/pearl creation process, small seed-like pearls would form adjacent to the nucleated pearl. These solid nacre byproducts that were formed by an Akoya oyster during the pearl creation also became known as keshi pearls.

The modern-day definition of a keshi pearl has morphed to encompass a vast array of pearl shapes, sizes and colors and is generally only limited by the qualification that the end-product pearl is non-nucleated. However, it would be a mistake to refer to the overwhelming majority of keshi pearls in today’s market as "natural". While the modern keshi pearl is non-nucleated, it is very much a product of human intervention in mollusks. In fact, the Chinese (and others) have refined multiple techniques to exclusively create various desirable sizes and shapes of keshi pearls.
The modern keshi pearl started as mishaps during cultivation when the mantle tissue separates from the nucleus. The nucleus is expelled, but the mantle tissue remains and the nacre grows into a keshi pearl. Other times, part of the implanted mantle tissue separates and a keshi pearl is formed alongside the nucleated pearl in a separate pearl sac. Once the keshi pearls became sought after, pearl farms began deliberately inserting only mantle tissue with no nucleus and producing only keshi pearls. Finally, the Chinese discovered that if the cultured/nucleated pearl is carefully removed during harvest, the undamaged pearl sac will produce a keshi pearl for a second harvest. This is very desirable to the pearl farms, since many species of mollusks will only produce one harvest of nucleated pearls.
Because they have no nucleus and can be produced in many types of mollusks, keshi pearls vary widely in size, shape and color. Since keshi pearls are all nacre, they are incredibly lustrous and shiny; in fact, most keshi pearls have greater luster than even the highest quality cultured pearls. The striking color ranges, the magnificent natural shapes, and the unbelievable sheen and luster makes the keshi pearl an especially beautiful gem to be used in handmade designer jewelry.
