Hint: Consider the concept that the flow of electricity is dependent on the presence of free electrons in a compound, and that the outermost electrons in diamond form covalent bonds, resulting in the non-availability of free electrons within diamond.

Due to its strong covalent bonding and low photon scattering, diamond, unlike most electrical insulators, is an excellent heat conductor. Natural diamond has a thermal conductivity of about $2200W{\left( {m.{\text{ }}k} \right)^{ - 1}}$ , which is five times that of silver, the metal with the highest thermal conductivity.
