Mikimoto 18ct White Gold Diamond 7mm White Akoya Pearl Necklace, PPL 351D W 11. Over a century ago, Kokichi Mikimoto succeeded in creating the world\'s first cultured pearl. His quest for perfection and his love for these pure, lustrous gems of the sea were the guiding forces that built the house of Mikimoto. This elegant Mikimoto necklace, from the Pearls in Motion collection, features 11 exquisite white Akoya cultured pearls, 7mm in size, that beautifully rest upon an 18ct white gold chain. The necklace is also detailed with 0.20cts of brilliant cut diamonds and the chain can be adjusted using a unique mechanism to create your ideal drop length. This necklace comes beautifully packaged in a unique Mikimoto presentation box with certificate of authenticity.
