In former days small irregular pearls were called Keshi (poppy seeds). Today the name Keshi is used for all sizes of irregularly shaped pearls, which normally consist of nacre.
Normally the pearl producers try to produce a round pearl. A round shell nucleus with a piece of mantle tissue is introduced into the oyster. If the oyster expels or displaces the shell nucleus during the growing process, the oyster will build up layers of nacre wherever a fragment of mantel tissue remains. This process will usually create a pearl with an irregular shape (as the pearl has no shell core). Such pearls are called Keshi pearls.
We offer Tahitian Keshi, Australian Keshi, Japanese Keshi and Freshwater Keshi.
