    This is a very interesting mystery. First of all, didn't you say
    that the diamond was in fact NOT damaged at all by two hours at
    900C? The pictures of damage at 2800C are really interesting--
    thanks for sacrificing the diamond! 

    So, in re the original loss of the stones in the bar in the PMC-- we
    seem to have no choice but to conclude that they were in fact not
    diamonds, but clever simulants. People have been fooled before, and
    simulants have been around a long time (I think I recall that they
    were from a vintage piece). No one wants to believe that their
    diamonds are not real, but it seems to be the only explanation that
    encompasses all the info we have. 

    Wait, now-- what metal was the bar they were set in? If it was not
    gold or plat, that would support the idea that they were not real
    diamonds. 

    I love a good mystery!
