Geb loses pretty hard since it works differently than Aqua Necklace: when Avdol attacked Geb with fire that fire evaporated the water and burned him, Aqua Necklace was evaporated and the user was just fine.

Given that parallel, I'd say Ghiacchio would defeat both of them. Geb being frozen would freeze N'Doul to death and even when Aqua Necklace's freezing wouldn't kill Angelo he would be unable to move (just like his stand) and when Ghiacchio discovers him he's dead.
