    Jeanne : I will be interested in seeing if you different responces
    than I got when I asked this question.To paraphrase: The people that
    know won't tell you and besides why do you want to do that. Are you
    trying to cheat people by enhancing stones? Some of my answers where
    off list some onlist but the above was the condensed replys. I too
    had some Amethyst I want to play with. It was a lower grade from
    California and I wanted to see what could be done. In researching
    this issue I am finding that it is more than just temperatures and
    time. Some stones seem to require different gasses in the
    environment. Normal air might cloud the stone or burn it but Argone
    might give you a stable color change. I too have not found any
    specifics and have even searched about 300 books that supposedly
    gave this kind of info. All to find that they did not give the info
    claimed. Good Luck and if you do fing something please share it with
    me either on list or offlist.
