    I wanted to take a part in this discussion before, but nuclear war
    on another thread kept me busy. 

    I am in complete agreement with Kevin. First there are different
    kinds of opals, some better than others. Most problems associated
    with what is called CT-opal type, but I want to address the subject
    of setting opals which was touched in the previous posts. 

    Opals are fragile, there is no argument about it, but consider this:
    Porcelain tiles are fragile too, but we tile our kitchen floors with
    them, and if mounted properly they can take a hit. 

    When mounting opals, the setting must not allow any movement of the
    stone, and must be massive. If fragile material prevented from
    flexing and moving while hit, it will not crack. That is why kitchen
    tiles, as fragile as they are, can survive when something heavy
    dropped on them.
