    I have also heard that the black diamonds now in the marketplace are
    irradiated, the black color hiding all the inclusions.  Thankfully I
    have no first hand experience to prove this, but I have also heard
    that heating these can alter the color and make all the inclusions
    jump right out. Another theory I don't want to test is that stones
    that are this badly included don't need to be heated to begin with. 
    I have had to set a few, as they seem to sell fairly well in our
    area, and I am wary of that, too.  The inclusions are not readily
    visible when setting, so I think it would be all too possible to do
    some serious damage by putting too much pressure in the wrong spot,
    pressure that would not normally be a problem in a decent diamond. 

    Jim in the mountains of NC where the rainy season seems to have
    settled in to stay for a while.
