Six black enamel with silver circle bracelets

Six rings of different widths Black enamel outside with silver inside Six rings with 3” circumference, I think it would be for a medium hand. There are 2 wider ones that are 1/2 “ and 3/8” in width and 5 thinner rings at 1/8” in width Lots of creative choices here! The silver from the back subtly shows at the front edge. A nice touch. Never worn, excellent condition From my personal vintage jewelry collection
