Реферат:	eng: It has been demonstrated that the high-pressure (15 GPa) treatment of shungite samples (Karelia, Russia) at a temperature of 1600 degrees C for 2 h transforms them to diamond. The comparison of the Raman spectra of the diamond material prepared from shungite and carbonado, which is a rare variety of cubic diamond sometimes called black diamond, has revealed their significant similarities. Our data indicate the possible growth of carbonado from the shungite-like natural material, which may be one of the ways carbonado appears under terrestrial conditions.
