John - In response to #2 below: some external agent

energy show up as "work done" on the external agent as
the pressure is released.

This would only be true if the volume of the diamond increases
very substantially, like by a factor of three, as the pressure is
reduced. In fact the volume of the diamond will increase
by a tiny fraction, perhaps 1% at most, as the pressure is
reduced. Thus the work done on the external agent will be a few
tens of joules at best.
