From my old high school chemistry days. I think that you meant "specific" gravity that I used. And again I'm not sure if that is the correct term to use. However, what I meant was that since things like iron are more "dense" than other things, the more "dense" elements / compounds should be at the center. Its what makes steel float in mercury.... That should IMO rule out the "diamond core" theory unless carbon is the "densest" element in the planet's composition.
