These pearls occur without any human intervention. If foreign bodies should, by accident, enter the host oyster then they will produce small derivatives which are also gathered in at harvest. These Keshi pearls do not have a nucleus and are therefore natural pearls in their truest form. The smallest Keshi pearls are no larger than a pin head and are known as seed or poppy-seed pearls. Keshi pearls from the south-seas and Tahiti can get to over 10mm long and lend themselves to the production of unique rings, pendants, earrings or broches.
Be they small or large, Keshi pearls are highly prized worldwide. In countries such as China, Hong-Kong or India they have been known to be ground down and used for medicinal purposes.
