FIELD: manufacture of diamonds. SUBSTANCE: essence of this method resides in introducing catalytic mixture into diamond-carbon mixture by treating mixture with either solution or vapors of one of vanadium-containing compounds at vanadium-mixture ratio of 0.001:0.05 parts by mass, and then thermally treating resultant product at air temperature of 390 to 650 C. EFFECT: greater simplicity of process of withdrawal of graphite and ecological safety. 1 tbl
