    Susan, I'm familiar but not experienced with casting in place. I have
    soldered on some thousands of diamonds, though. Generally speaking,
    in heating diamonds if anything is going to go it's not the
    inclusions, it's the cleavages that will get you. And I was always
    told not to heat colored diamonds because in some cases the color is
    related to heat - that may or may not be actually true, but we just
    never did it because it's an expensive experiment. I don't think
    black diamonds would be a problem - just a gut feeling. Hopefully
    someone with cast in place experience will get back to you, too.
