Mikimoto 18ct White Gold Diamond 7.5mm White Akoya Pearl Drop Necklace, PP 20226D W. 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 classic Mikimoto necklace features an exquisite white Akoya cultured pearl, 7.5mm in size. The pearl hangs gracefully from an 18ct white gold chain which is embellished with a 0.08ct diamond, adding a sophisticated sparkle to the piece. The pendant is completed with a secure 18ct white gold chain, adjustable from 40 to 43cm in length. The necklace comes beautifully packaged in a unique Mikimoto presentation box with a certificate of authenticity.
