The Higgs vacuum is a metastable state with lifetime longer than the age of the universe, but the vacuum can be destabilised by microscopic black hole seeds. The nucleation process is a nice example of black hole thermodynamics. We would not exist today if the universe contained any microscopic black holes, and this puts limits on the primordial black holes, the standard model and collider black holes.
