    According to Jon Sinkankas' "Gemstone & Mineral Data Book", peridot
    is attacked by warm sulphuric acid, and is best not treated with any
    acids whatsoever.  Seeing as pickle is basicly sulphuric acid, pickle
    and peridot make for a bad combo.  Probably the only thing that can
    be done to the stones is to recut or maybe repolish them.
