Keshi and Mabe Pearls
What are Keshi and Mabe Pearls
KESHI PEARLS

The name Keshi comes from the Japanese
word for poppy seed. Originally they were small "chance" pearls
produced while the main cultured pearl was forming. Now Keshi usually
refers to larger "chance" pearls (up to 10mm), created in giant Pinctada
oyster shells. Often highly iridescent, their shapes are intriguing and
irregular (baroque).
MABE
PEARLS

(Japan, Indonesia, French Polynesia,
Thailand, Mexico, Tonga and Australia) Unlike the majority of cultured
pearls, Mabe are "blister" pearls that grow attached to the inside
shell of the oyster (Pteria penguin - the black-winged pearl oyster, and
others). This creates their distinctive flat base and semi-sphere
shape. Also known as dome, button or assembled pearls, extra support is
added to the pearl structure after removal from the oyster. They are
today's "half-pearl", 20-25mm in diameter.
