This is genuine mabe pearl from Pteria Penguin / black winged pearl oyster shell.
Mabe Pearls Develop On The Shell Cultured mabes are grown intentionally, by using a hemispheric nucleus, rather than a round one; and by implanting it against the oyster's shell, rather than within its tissue. The pearl then develops in a hemispheric form, with a flat back. While in the oyster a mabe pearl is actually considered a blister pearl not a mabe pearl. I did not make these myself, these where brought in on trade.
Creating Mabe Pearls After the blister pearl has developed, it is 'worked' to become a mabe pearl. Blister pearls are ‘worked’ by cutting the pearl out of the shell with a circle-bit drill. The nucleus is then removed and replaced with a resin. The back of the pearl is then capped with a piece of mother-of-pearl to complete the mabe pearl.
Mabe Pearls, Perfect For Jewelry Cultured mabes are used for such things as rings and earrings, rather than for stringing on necklaces. They tend to be very beautiful with high luster and orient, but are priced much lower than round pearls. Reference- http://www.pearl-guide.com/mabe.shtml
