    Would like to ask your opinion...... Regarding the opal thread - 

    I received a ring as a gift about 10 years ago.  It was made by a
    local artisan. I was told that the center stone is a triplet - a
    round opal sandwiched between a lower layer of black onyx, and the
    top layer being clear quartz. 

    My question is, will the quartz layer prevent fissures or cracks
    from occurring inside the opal, or will it merely provide some
    protection against abrasion? 

    I also admit that although the quartz layer has become abraded, I am
    hesitant to have it polished, as I am not sure if this might heat up
    the opal or damage it. 

Any opinions shared would be welcome.
Sincerely,
Mary Beth
