GIA and Mikimoto have a history of working together to resolve industry issues. During the 1990s, researchers from both organizations studied unusually large (10+ mm), near-spherical, freshwater cultured pearls from China that were causing many to question their nucleation process. The joint investigation concluded, however, that they had been created through traditional tissue nucleation.
Cultured-pearl pioneer Mikimoto (America) Co., Ltd. Has donated $120,000 to establish the Mikimoto Pearls Course Scholarship at the Gemological Institute of America—a first at GIA. In recognition of the gift, Mitsuhiro Mitsui, president of Mikimoto (America) will be inducted into the League of Honor at GIA’s annual dinner on Sept. 19 in New York.
This course examines how to buy and sell akoya, South Sea, Tahitian and freshwater pearls with insight and skill; and GIA’s 7 Pearl Value Factors™: size, shape, color, luster, surface quality, nacre quality and matching. You will be taught the difference between natural and cultured pearls, postharvest treatments, imitation pearls and pearl testing. The final exam is online, open book and does not require a proctor.
