Diamond anvil cells and maximum pressure

tech-art

I was checking out diamond anvil cells and i have few questions.
I have been on this sites:

1.what is max pressure you can make in dac?
2.how can dac works at 100GPa if compressive strength of diamond is (1)8,680-16,53 GPa, (2)43,72GPa ?
3.What determines how much is max dac pressure?
