Mabe pearls, also known as half pearls, are dome-shaped or hemispherical pearls cultivated on the inner shell of a mollusk rather than in its body. Mabe pearls are typically used in settings such as earrings or rings that conceal their flat backs.

Mabe pearls are grown in Japan, Indonesia, French Polynesia and Australia. Mabe pearls range in color from light pink to rose to bluish.

Another dome-shaped pearl is the blister pearl, which is a freshwater pearl.
