Hi Mark,

    That's useful to know, that peridots are sensitive to acids. 

    My worst stone disasters have been caused by sheer stupidity on my
    part. I know full well that if you heat a stone and then quench it in
    cold water you are exposing it to thermal shock and that it WILL
    shatter. But when annealing and soldering numerous times everyday, it
    has now become a reflex action to quench in water afterwards, and
    when I've occasionally had to solder something with stones still in
    place (diamonds, sapphires, rubies or CZ's), although I've
    repeatedly told myself "don't quench, don't quench" I have sometimes
    done exactly that, and heard that horrible sound of the stone
    shattering. I think I've done it on about three occasions and in each
    case it was always a favourite stone I only had one of!!! 

    Thanks for the tips.
