Vintage/Antique Silver Plated Butterfly Green Oval Stone Intaglio Signet Ring

Size 8 Probably green agate stone, maybe brass base with a silver plating…style could be Roman 15x20mm setting Good condition with some signs of wear, butterfly has a little chip on one of the bottom wings, the silver plating has started to give way to the base metal in some areas…I’m thinking it will age into a nice two-tone piece 🤞 Bundle to save, and send offers!
