Used puzzle ring, made with very thin silver links. I measured using a measureing tape its about 47mm (put it on my finger and where it fit I then measured around my finger). Hasnt been worn in many years. I remember a couple links bent over the years and were removed from the puzzle, possibly may look like a link is missing depends on how you view the ring :). Believe its sterling silver but cant be sure as I dont see a mark and I am not taking the tie off. FYI the reason its tied is it will fall appart and the puzzle is very hard to put back togeather.
