    On the subject of Mexican opals... 

    Is there a hardness/durability difference between the transparent
    ones and the red ones? I really don't know anything about them, but I
    picked up three tiny (approx 4mm?) ones for a couple bucks from a
    recent gem show just cause I liked them. Two are clear with really
    nice fire in all directions and one's red and doesn't really have
    much of any fire. Should I be handling the colorless ones with more
    care? Am I supposed to be keeping all of these in water? Or are they
    all equally chancy and I might as well leave them stored dry in the
    little plastic case to see whether any of them are stable enough to
    use for jewelry? 

    I guess I should add that I'm in Hawaii, so the atmosphere isn't as
    dry as other places.
