What are keshi pearls?

Are they natural or are they cultured?

Well, they're a little bit of both!

Keshi pearls are not cultured, but are a byproduct of the culturing process.

Like natural pearls, keshi pearls are non-nucleated. This means they are made entirely of nacre.

Keshi pearls can have very strong orient (multi-colored, iridescent overtones).

Keshi pearls can occur in both saltwater mollusks and freshwater mussels.

Keshi pearls are usually caused by a mishap in the culturing process where the grafted mantle tissue separates from the nucleus.
