Abstract: A method of producing polycrystalline diamonds which is characterized by providing a thermal contact of the reaction chamber with the cooled members of the device developing a high pressure and high temperatures for removing the heat generated within this chamber in the process of crystallization of a diamond, which method is also characterized in that the cross-sectional area of the metal-catalyst is not more than 0.04 that of the reaction chamber in a plane normal to the direction of the maximum withdrawal of the heat of crystallization. Said metal-catalyst is set in the carbon-containing material substantially in the center of the reaction chamber.
