Up for auction is this Vintage Large Mens Sterling Silver Flying Bat Smokey Quartz Ring. I beleivethe stone to be smokey quartz but I'm not 100% sure. The ring weighs in at 17.5 grams on my scale. The piece has incredible character with its bat with flying wings that go almost all the way around. The dimensions of the face are approximately 20.5mm tall by 24.5mm wide about half way down the ring. The ring is approximately size 8.75-9 on my ring sizer but feels like a 9.5. The piece looks even better in person!
