These are natural rubies and sterling silver. I do not have paperwork. They aren't that expensive and I auction them all the time. I have good feedback if you look people have been very satisfied with my rings. I am not a jeweler. I only pass on what I am told about these rings. I don't think you will be dissatisfied. I also auction gold filled which is a less expensive but nice alternative to the real thing. Lots of happy people with those too. I really don't think you can expect more than this from listia. If you want papers you should go to a jewelry store. I think my rings are quality for what they are. Thanks
