      Monte-Carlo calculations of diamond thermodynamic properties have been carried out to check correctness of graphite and diamond semiempirical equations of state (EOS) in the regions of phase diagram where experimental data are absent.
      On the basis of these EOSs and Grover’s model of liquid state EOS of liquid carbon have been constructed and carbon phase diagram (graphite and diamond melting curves and triple point) has been calculated. Comparison о calculated and experimental Hugoniots has stated a question about diamond melting curve.
