So this is not a good time to be "investing" in diamonds, or indeed, in
gem stones in general. (I bought a "Chatham emerald" for my first wife's
engagement ring over 30 years ago. The jeweler said a pro could spot a
Chatham as synthetic because it has _fewer_ flaws than a natural stone. It
was a glorious stone and I could have cared less that it was pressed in a
factory and not a mountain in India.)
And maybe when diamonds inevitably collapse in price, we'll get those heat
sinks.
First, I'm pretty sure you *need* artificial diamonds. I'm pretty sure
that natural diamonds have too many impurities and it messes up the
phonon transport.
Besides, aren't carbon nanotubes higher in thermal conductivity? (Since
the whole reason why diamond has such an unusual thermal conductivity is
phonon transport, carbon nanotubes do better at this.)
We're more likely to get nanotubes to production given the other
applications before monster chunks of diamond.
