EUC! Could use polishing. Has Ethiopian Opal. Gold spinners appear to be brass? Ring is 925 silver. Size— see photos. I wear as 6.25 and this fits. I would say best for a size 6 as the thickness of the band does make it tight on my finger when they swell with heat. It appears the bottom goes to a 7.5.. this does NOT fit a 7.5! A 6 is best to avoid it getting stuck with swelling during heat. Tagging spell for exposure!
