I will try to help you. First get a magnifying glass. Look all over jewelry for any number's and names. Number's with a K after it means it's gold real gold. look for the word Sterling and set them aside. Make freinds with a jeweler preferably in a small town and ask for his help when he's not busy Some stones can be also valuable and any old watches and cuff link's. Get some professional help with this or your grandfather will turn over in his grave. OK? http://rbcompilations.com/
