    Harriet - here's a good link to Wikipedia about synthetics:
    http://en.wikipedia.org/wiki/Verneuil_process#References 

    This is one of those topics that we all find interesting if not
    fascinating, but of course without seeing the stone we're all just
    guessing - me, too. To me what's going to tell you right off whether
    it's quartz or sapphire is the lustre - quartz looks like glass and
    sapphire has a sheen to it that's unique. One other telling thing is
    that if it really is that old, as you say, if it was worn at all an
    amethyst would be really beat up, unless it has been recut - sapphire
    will last much, much longer. Seeing it is the key, though. It could
    be something entirely different than anybody here thinks - some
    stray, arcane stone that some lapidary found years ago. There's no
    telling without actually seeing it.
