Mabe Pearls: A Dramatic Dome The mabe pearl gets its name from the type of mollusk in which it is grown, the Pteria penguin, which is called "mabe-gai" in Japanese. A mabe pearl is actually a cultured blister pearl that is grown differently than other cultured pearls. Instead of being grown inside the body of a mollusk creature, a mabe pearl is grown against the inside of the shell. This allows the mabe pearl to develop a dome shape with a flat back, and is why mabe pearls are sometimes referred to as "half pearls". Used, has some denting at the had side of the ring shank from wear. RIng has an oxidized look intended by the designer.
