This was from my Granny's collection, so I don't know much about it *Appears to be Real Opal and Turquoise set in Sterling Silver.☺️ *It was tarnished so I cleaned with Silver cleaner, some of the Oxidation is still on. I'm assuming that's part of the design. *Size 8.5, sizeable *I don't see any markings on it ♥️ It's not my style, but the Gemstones are so beautiful, I hope it goes to a good home. *Please feel free to ask questions
