We report the results of an experimental study on diamond crystallization in the Sb-C system under HPHT conditions. The experiments were run at pressures of 6.3 and 7.5 GPa in the temperature range of 1500-1800 °C for 1 to 40 h. Diamond crystallization via spontaneous nucleation and growth on the seed crystals has been established. It is shown that the kinetic factor plays a crucial role in diamond crystallization in the Sb-C system. For run duration of 40 h the minimal P-T parameters of diamond growth on the seed crystals are found to be 6.3 GPa and 1500 °C, while the minimal parameters for spontaneous nucleation are 7.5 GPa and 1600 °C.
