Consider the energy diagram for the reaction a(g) b(g). The stable form is the one with the lowest Gibbs free energy. At 300 K, the enthalpy difference between diamond and graphite is Ahd-g = 1900 J/mole, with diamond less stable than graphite in this regard. Being a highly ordered structure, diamond has a molar entropy lower than that of graphite, and Asd-g = -3.3 J/mole-K (see Fig. 3.6).
