Mikimoto 18ct White Gold Diamond White Akoya Pearl Vine Necklace, PP 1810D 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 Mikimoto necklace is an elegant piece that features a marquise shaped pendant with an 18ct white gold vine running within. The vine is embellished with 0.11cts of brilliant cut diamonds and three white Akoya cultured pearls, that ascend in size from 3.75-4.5mm, creating this wonderfully elegant floral piece. This necklace comes beautifully packaged in a unique Mikimoto presentation box with certificate of authenticity.
