The only really consistent thing is that when a CoG is killed, it begins to smoke. It may not dissolve completely based on comments by Nora and Peter Port about how they sold the fur of the Grimm they killed or mounted them on a wall. However as said before, the CoG aren't really like other lifeforms on the planet and could be a type of physical ideal. Based on this, when they are killed their essence may scatter and either form a new Grimm or maybe pass their power on to other Grimm to increase their power.

A good example of this is the movie The One (bad movie, but works well for this example). In the movie, Jet Li's character travels to different multi-verses in order to kill other versions of himself, resulting in himself and other versions of him to gain some of that power. Grimm may work the same way, when one is killed their power is absorbed by other nearby Grimm unless there isn't one nearby; in which case a new Grimm is created.
