This is interesting! I've seen artists paint with gold leaf paint they mix themselves (gold leaf with some kind of solvent). I wonder if you could do something like that and seal it afterward. I'd do it on earrings maybe, since they don't get touched too much, but I'd be afraid of it wearing off of the pearl.
Or hmm mixing gold leaf with some kind of resin so it cures hard....
