What is Keshi ?

Formation of keshi
Keshi is created when the oyster rejects the nucleus (the spherical nucleus) and only forms with small piece of graft (piece of the mantle of a pearl oyster) within a carrier pearl oyster. They can also be cultivated intentionally, which means that the graft is inserted during the process. The result is 100% mother-of-pearl.
Keshis are sought-after in jewellery for their originality and those in Tahiti are considered as exceptional pieces.
Size and shape
They have a diameter between 1 and 15 mm and all types of forms but are mainly baroques.
