The only "jewelry store" I've ever seen that had actual vintage jewelry was either a specialty antiques shop or ross-simons.com, which is an online jeweler that does a lot of older pieces mixed in with the newer stuff.  Everything I've ever ordered from there has been excellent quality, but I've always gotten newer jewelry from them.  They have a good return policy if you don't like it, but you'd have to check on whether it applies to the older jewelry as well.  Good luck!And thank you!
