Gorgeous Vintage Circa 1980s Vintage Sterling Silver Carved Shell Cameo and Onyx Flip Ring. Please excuse reflections, all is in Excellent Vintage condition. Size 9.5. The Hallmarks read VINTAGE STERLING & there's a picture-like Hallmark that I can't make out. I know these were Extremely Popular in the 1980s so, I recall these marked VINTAGE coming out on the market.
