Mikimoto 18ct Rose Gold Diamond 7mm White Akoya Pearl Ring, PRH 5473 Z2. 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. Elegantly sitting within a floral design, this stunning 7mm white Akoya cultured pearl rests next to a floral dandelion setting, which is adorned with 0.06cts of brilliant cut diamonds. The ring is completed with a solid 18ct rose gold band, making this perfect for everyday wear.  The ring comes beautifully packaged in a unique Mikimoto presentation box with a certificate of authenticity.
