I cant find any mark so Im going to say no just to be on the safe side. Like I said, my mom wore them and she is allergic to anything that is not real but I dont want to say they are and have them not be. So, no I dont see any markings on them.
Just in case you miss it,some times its put on the post,hing,clasp,just want you to get all you can if they are real,but i like them any way,i hope this helps you be able to get whats fair to you
