Coral Ring - Engraved Sterling Silver - Vintage

Fabulous huge natural Coral cabochon ring in a phenomenal setting. There is so much detail in this ring. Top has ornate design around stone and then sides have a shield-like design and band is double and looks like bamboo. Stone moves a tiny bit in setting so you can hear a bit of movement, but it is secure. Has a tiny hallmark but it's hard to make out. Sold to me as Sterling silver. Ring size = 7.5 and cannot be sized based on ornate band.
