Zusammenfassung:	PCT No. PCT/SU80/00083 Sec. 371 Date Apr. 30, 1981 Sec. 102(e) Date Apr. 20, 1981 PCT Filed May 30, 1980 PCT Pub. No. WO81/00560 PCT Pub. Date Mar. 5, 1981.A process for growing diamonds from carbonaceous compounds at high temperatures and pressures within the range of thermodynamic stability of diamond in the presence of metals-catalysts-solvents and active compounds. As such active compounds use is made of cyanamide and/or its metal derivatives of the first, second or eighth Groups. The herein-proposed process can be employed for manufacturing diamonds fit for use in the tool-making industry and in solid-state (semiconductor) instruments.
