I have tested this theory on several different pieces of jewelry. I apply a layer of liquid foundation on my forearm. let it dry. i would firmly place the jewelry against my skin and drag it across the makeup covered area. if it leaves a green or black streak, it definitely has some kind of gold on the surface. that does not tell you if it is solid, plated, or what karat. only that it has gold on it.
