Vintage ring from Germany with a large dog tooth prong set blue rhinestone. Ring is adjustable and set at about a size 6 right now. The band is twisted like a rope and the prongs are fancy dog tooth style. The large blue glass rhinestone is open back and measures about 7/8" across and about 1/4" thick. Ring is stamped Germany on the back of the stone setting. Metal is gold tone in color, may be brass, not sure.
Ring and stone are in very good condition.
