So unique. This must be the most unique ring I have ever seen. It's made of an intricately decorated piece of brass that is molded to fit over a silver shank accented with a faceted emerald stone. (The metals and stone were confirmed by a jeweler.) The marking inside is simply "China" which dates the piece to the early 1900s, an era of Chinese imports. The size is 11.5. The ring fits my index finger or thumb. If you are looking for something vintage and totally different, this item is perfect for you.
