    Default pearl's death

    Are there any studies to explain pearl's death phenomenon? I have experimented a new glue, polymerizable under UV exposure, on a test pearl : some solvent in this glue kills instantly the pearl, up to deeply under surface, and I wonder how deep it does... It's known that aragonite is unstable and always turns in calcite after a long time, or quickly in specific conditions. Would it be possible that it is such a physical reaction which kill pearls, or is it conchyoline which is deeply attacked and stop to stick aragonite crystals?
