This HALF OUNCE cast pattern, sterling silver ring with turquoise and mother of pearl stones is a size 11 3/4 (I can get it to a 12 if needed). A friend donated it and the stones are cemented in, thus, it cannot be sized down as it will compromise the stones stability.
The top width is 23mm and tapers to a 5mm at the bottom of the ring shank. Antiqued to show detail. This one's a beauty!!
