I don’t know anything about this. It did have a sticker that said genuine opal but it has fallen off somewhere. Clasp works as it should. I have not taken it out of the box but I did check the clasp. I can’t tell if it’s signed or not. Has very normal, minor wear due to being moved around. Looks like it has never been worn. Please see photos as they are part of the description. Ships as soon as payment is received All offers welcome! Thanks for looking!
