Dark blue greens and gold flat donut shaped 2 1/2” circle centerpiece of carved stone 1/2” cut out inside the donut And above this striking art piece is stacked 1” carved green round stone, 3/8” rust round stone and 1/8” green very small donut stone All attractively tied together with adjustable black cord. 17” total in length I bought this inspired necklace in San Francisco’s Chinatown. From my vintage jewelry collection, and in excellent condition and quality. A statement necklace from the 90s!
