Diamond heat spreaders for ICs are available.[1] There are problems with coupling the heat to the diamond, and with the various materials having different rates of expansion. It hasn't really caught on. Diamond layers within ICs to help get the heat out are being considered for future GPUs.[2] Again, it's not a magic bullet.
