What is a Keshi Pearl?Why is it known as a “mistake”?
A.Keshi pearls are small non-nucleated pearls typically formed as by-products of pearl cultivation.A Japanese word also meaning “poppy”, it is used in Japanese for all pearls that grew without a nucleus. Originally, keshi pearls referred to those pearls formed when a bead nucleus was rejected. More recently, keshi has been used to refer to second harvest pearls and even to freshwater non-nucleated pearls. However the later usage referring to freshwater pearls is considered erroneous by many leading gem trade associations. Because they have no nucleus, keshi pearls are composed entirely of nacre and thus the creation of a keshi pearl is known as a mistake.
Pearls on a half-shell?
A.Many people mistakenly think that their next plate of oysters on the half-shell might contain a gem. But unlike pearls of gem quality created by pearl oysters, pearls produced by edible oysters have low luster and resemble pebbles. Edible or "true" oysters, the type most commonly eaten, are not as closely related to pearl oysters as their names imply. Both are marine bivalves with similar anatomies and modes of reproduction, but they belong to different taxonomic families.
Members of the family Ostreidae, these true oysters cement themselves to hard surfaces and can live in estuaries with low salt content. They are raised and harvested as a desirable food source.
