Keshi Pearls



Keshi pearls also known as poppy seed pearls or seed pearls, as "keshi" means poppy seed in Japanese. Keshi pearls are usually quite small in size, and they do not have nuclei upon which the shape of a pearl is usually determined. Keshi pearls also come in a variety of different colors and shades and are known for their high luster. Keshi pearls are quite unique in the way they are formed. When compared to the standard method of pearl formation, Keshi pearls are formed when the oyster rejects and spits out the implanted nucleus before the culturing process is complete. Because the oyster has expelled the implanted nucleus of the pearl, the resulting keshi pearl is 100% the mother of pearl. This gives it an especially lustrous and shimmering surface quality. Most keshi, in fact, have a greater luster than even the highest quality cultured pearls. It is the reason the market is seeing more Keshi jewelry.

Keshi pearls are a rare find today. This is due to Tahitian and South Sea pearl farms now x-raying oysters to determine whether or not the nucleus has been expelled. When a nucleus-free oyster is found, they are then re-nucleated before a keshi has time to form. This practice has made keshi pearls much rarer than they once used to be.

Keshi pearls are usually used with peanut shaped pearls to create exquisite jewelry.
