Antique STERLING Silver Art Nouveau Black Onyx Cab Ring Size 4 * Signed. This ring is pretty with lovely detailing, please note the flowing leaf design on each side of the stone. It has a Sterling Hallmark & a Maker's mark (which I'm not familiar with), see pic. Also, this ring does test positive for sterling silver. It is in good used condition with wear, light surface scratches, & a touch of tarnishing. Thanks for looking.
