WHAT IS A KESHI PEARL?
Keshi pearls are a byproduct of the natural pearl development. Usually it happens when the oyster or mollusk spits out the pearl sac before the pearl is finished turning into a round piece. This can happen in both the freshwater and salt water pearl-making-process. Though they were originally undervalued, now there is a market for them and the Eastern suppliers drill them to sell. Here’s a few pictures of what keshi pearls look like: http://www.experts123.com/q/what-is-a-keshi-pearl.html
Keshi pearls are created naturally in the soft tissue of most cultured pearl-bearing oysters and mollusks. Keshis are usually formed by the accidental intrusion of sand or shell. Keshis are considered a valuable by-product of a harvest. The smaller Keshi pearl is not much larger than a pinhead, and is often called a “seed” or “poppy” pearl.
