Mikimoto 18ct Yellow Gold Diamond White Akoya Pearl Clover Necklace, PP 20201D C. In 1893, Kokichi Mikimoto succeeded in creating the world\'s first cultured pearl and ever since, his love for these pure lustrous gems of the sea has been his motive behind the brand of Mikimoto. He is now world renowned as the primary producer of the finest quality cultured pearls and a world leader in sophisticated and feminine pieces of jewellery. The Mikimoto Clover Collection takes it inspiration from the luck of the rare four leaf clover by designing a single white Grade A+ Akoya pearl, 5.25mm in size, into one of the four leaves. The remaining three leaves are finished in soft autumnal colours of 18ct white, yellow and rose gold. This floral piece features a 0.02cts diamond adorning one of the leaves of the four leaf clover which hangs elegantly on an 18ct yellow gold chain.  This necklace comes beautifully packaged in a unique Mikimoto presentation box with a certificate of authenticity.
