This fresh water pearl, aquamarine, and square semi precious stone necklace was designed by Kazuko Oshima, who passed away in 2007. Kazuho designed elegant jewelry exclusively for Barneys NY. Her rare, one of a kind jewelry pieces combined the delicacy of wire with the solidity of stones. She believed that the materials she worked with possessed great healing powers. This rare Kazuko necklace comes from the collection of the influential New York art dealer Holly Solomon.
