About Mikimoto:
In 1888, Mikimoto obtained a loan to start his first pearl oyster farm at the Shinmei inlet on Ago Bay in Mie prefecture together with his wife and partner Ume. On 11 July 1893, after many failures and near bankruptcy, he was able to create the hemispherical cultured pearls. He introduced these mabes at a marine products exposition in Norway in 1897, and began an export business. However, it took him another 12 years to create completely spherical pearls that were indistinguishable from the highest quality natural ones, and commercially viable harvests were not obtained until the 1920s.
Mikimoto building in Tokyo, Taishō. Mikimoto did not know that government biologist Tokishi Nishikawa and a carpenter, Tatsuhei Mise, had each spent time in Australia and learned the secret to spherical pearl production from expatriate British marine biologist William Saville-Kent -- that inserting a piece of oyster epithelial membrane (the lip of mantle tissue) with a nucleus of shell or metal into an oyster\'s body or mantle causes the tissue to form a pearl sack. The sack produces nacre, which coats the nucleus, thus creating a pearl. Mise received a 1907 patent for this grafting needle. When Nishikawa applied in the same year, he realized that Mise had already secured a patent. In a compromise, the pair agreed to cooperate, calling their discovery the \"Mise-Nishikawa method\". Mikimoto had previously received a patent in 1896 for producing hemispherical pearls, or mabes, and a 1908 patent for culturing in mantle tissue, but he could not use the Mise-Nishikawa method without invalidating his own patents. Mikimoto then altered his patent application to cover a technique to make round pearls in mantle tissue, which was granted in 1916. However this method was not commercially viable. Mikimoto finally made arrangements to use Nishikawa\'s methods after 1916, and Mikimoto\'s business began to expand rapidly.
Just before his death, Mikimoto was awarded the Order of Merit (First Class) by the Japanese government.
On 21 September 1954, Mikimoto Kōkichi died at the age of 96. He was posthumously awarded the Grand Cordon of the Order of the Sacred Treasure.
Mikimoto was also the official jeweler of the Miss USA (2003-2008), Miss Universe (2002-2007) and Miss Teen USA (2001-2008) pageants, under the Miss Universe Organization.
