Mikimoto 18ct Yellow Gold White Akoya Pearl Bubble Earrings, PE 1408 K. 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. These Mikimoto earrings feature a cascading cluster of six white Akoya cultured pearls, ranging from 3.25-3.5mm in size, to create this elegant bubble design. The earrings are completed with secure 18ct yellow gold post and butterfly fastenings, for easy everyday wear. These earrings come beautifully packaged in a unique Mikimoto presentation box with a certificate of authenticity.
