Wait... Is it not that within our current understanding of physics gold can only be manufactured artificially from an already heavier metal? (which are already more expensive than gold I think). I don't know the details but, basically, it's not because we can manufacture synthetic diamonds that we'll one day be able to manufacture non-radioactive synthetic gold.
