Vintage sterling silver mens' United States Maritime Service ring, very heavy, with superb detailing. I am guesstimating that the finger size is approximately an 8. The ring is more than substantial enough to be sized. The top of the ring measures approximately 13/16" x 13/16". The seal on top reads "United States Maritime Service" around an anchor on shield design. Please note- I ship only by U.S. Priority Insured mail. U.S. bidders ONLY. Good luck!
