I am quite surprised that diamond has this much 'hysteresis' as it it

Wouldn't we expect the expansion on release to be pretty close to the
initial compression.

I don't understand your question. It's not a matter of
hysteresis; its purely a matter of compressibility. I would
expect diamond to compress and expand by about the same very small
amount. It might take a few tens of joules of work to compress
1 cm^3 of diamond to 50 kbars (=5 kJ/cm^3) and about the same
amount of work would be done *by* the diamond as the pressure is
removed.
