We call this a signet ring because the top panel would be an excellent platform for your initials and the sides offer a delightful design to enhance the overall effect. There is a full English hallmark indicating that the ring was made in Birmingham, England, is 18K gold and has a date mark of 1917. There are additional maker’s initials, but they are partially worn and cannot be identified. The ring is size 5 ½ and could be resized. The hallmarks should not be harmed in the resizing process. The top measures ¼ inch in width. The bottom of the shank is 1/8 inch in width. The shank graduates gradually from the top to bottom. Lovely condition.
