Other Cultured Pearls
In addition to the main types of pearls mentioned previously, there are different types of pearls that are called; Mabe pearls, Keshi pearls, Circle pearls, and Abalone peals.
Mabe pearls are hemispherical cultured pearls grown against the inside shell of an oyster rather than within the body. They are generally used in ring, earring, and pendant settings which cover the flat backs or reverse side. Mabe pearls are cultivated in Australia, French Polynesia, Indonesia, Japan, and Philippines.
Keshii means tiny in Japanese and Keshii pearls are usually small. Keshii pearls, though not nucleated cultured pearls, are created by accident as a result of the culturing process and thus must be considered cultured pearls. Their unusual shapes and sizes are best in unique jewelry.
