FIELD: diamond production. SUBSTANCE: invention relates to principle of heterogeneous liquid-phase diamond crystallization occurring on heterogeneous surface of catalyst. In the process of high-temperature dehydrogenation of solid hydrocarbons of bitumen-resins and asphaltenes catalyst performs hydrogen chemisorption in atomic form on the surface. Chemisorbed surface of catalyst exhibits essential property for diamond crystallization providing the growth of crystalline carbon- -diamond. Invention describes method of practical realization of this principle. As a result, above 3000 carats of diamond crystals is obtained of different fraction with size from 100 micrometers to 1000 micrometers. The most values of diamond crystals isolated in experiments performed are 3.5 x 3.5 mm. Experiments did not propose to obtain diamond crystals of maximal value. EFFECT: improved method of diamond crystallization. 4 dwg, 1 ex
