Large Round Chrysanthemum Necklace with Red Copper. Sterling silver and patinated copper necklace with pierced chrysanthemum design on a sterling snake chain. The design is inspired by Japanese katagami which were used to silkscreen kimono fabric. In this necklace there is a hand made bezel holding the copper and the pierced silver pieces on the back to protect the skin from the copper. All pieces with patinated copper will vary due to the unpredictable results of the patination process.
