Mikimoto 18ct Yellow Gold Golden South Sea Pearl Necklace, MKM-464. 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 two uniform grade A+ Golden South Sea pearls which are suspended from an 18ct yellow gold chain, creating this beautifully modern and simplistic design. This necklace comes beautifully packaged in a unique Mikimoto presentation box with certificate of authenticity.
