HUGE Sterling Silver Angel Wings Biker Sturgis Sting Ray Leather Ring 12

Purchased in Las Vegas and mostly sat in a drawer. Heavy sterling silver ring stamped 925 and USA. Tried searching for the maker’s mark but no luck. Looks like a GI. Has a sculptural angel protruding in silver, she’s revealing her breasts and has long flowing hair. A maroon layer of sting ray leather inlay surrounds her wings and torso. Retailed over $700 many years ago.
