I don't understand, and if you could illuminate it would be very helpful, how are such pressures achieved and maintained even for the shortest time without destroying the apparatus that holds it?

These are generally done with diamond anvils which concentrate force on an extremely small area.

I understand that but it sort of dodges the issue that such enormous pressures must exceed the strength of any material, however small that pressure is contained in.

The compressive strength of typical diamond is about 470 GPa, so no this is very well within the strength of the material. The current record for highest compression achieved in a lab is 770 GPa using a special form of diamond.

Note to silent downvoters, this is what an answer looks like.

(Thanks jjk166)

Wikipedia provides a nice overview:

Contra the diagram, I don't believe the diamonds in a real anvil are faceted.

According to the wikipedia article you link, they are usually faceted with 16 faces (under "Force Generating Device")
