Who is Mikimoto?

Mikimoto Kokichi is widely known as the father of modern pearl jewelry. Born in a simple family whose business is noodle shop in Japan, Mikimoto had down to earth foundations. History will speak that he first had contact with pearls when he was still a teenager selling vegetables for his family when he met divers unloading the precious pearls out of their boat to the harbor.

In the year 1888, when there was a call from the government concerning the of pearl producing oysters, he began venturing into possibilities of breeding and cultivating pearls. He, together with his wife Ume, was able to produce their first cultured pearl in 1893. Years later, he began unwinding half spherical pearls in expositions like one in Norway. But it took him several more years before he finally receive a copyright in producing round pearls. To eliminate chances of competitors, he bought the rights of Mise-Niskikawa’s method of pearl production to completely own the rights of pearl production.

Having much of his history, his most important contribution in the pearl industry is by perfecting the methodology of using a round nuclei cut from American freshwater shells. This particular process is currently being used in most of the cultured and synthetically prepared pearls.
