Sterling Silver ring size 6-6.25 spinner ring, stamped 925 and Mexico (tried to show in pic but it's blurry), which almost always means designed by Taxco. Spinner rings are sometimes called fidget rings, the center band can rotate/spin separately from the rest of the ring. Great for anxiety relief etc. It's a well made, heavy ring with lovely scroll work in the center and beading along the top of the spinning band. Spinner works perfectly, it is vintage with a lovely patina so I did not clean it, but can easily be polished if requested.
