Hmm, I really don't know much about diamond treatments but I'll post what I think is right anyway, that is how I learn These are some enhancements, I'm sure that there are more. You can find what is done with each online easily by just searching the term.

HTHP treatment -- stable, nice colours, a good option for tight budgets from what I have read.
Irradiation or irradiation+annealing -- Safe. In greens and blues. Quite sure it is stable.
Coating -- bad, wears off
Heating -- I think mostly in black diamonds, though annealing consists of heating the stone too.

Clarity treatments:
Clarity enhancement -- makes the diamond more susceptible to high temperature and acids, I see people advising against these on PS.
Laser drilling -- not so sure about this, I think it is a type of fracture filling.

I think all are stable, with the exception of coating, which can scratch off.

Black diamonds are often irradiated.

Good synopsis!!
