Relevance and purpose of the study. For the first time the geological literature on diamond provides a comparison of the latest data on diamond synthesis and hypothesis of kimberlite pipe formation. Method of study is the analysis of data on kimberlite pipe origin. It is noted that only one hypothesis, an electric discharge pipes origin, corresponds to the results of laboratory studies of diamond synthesis by electric discharge. Since the end of the 50s of the XX century the electric discharge method for diamond synthesis is used in many countries and it is recognized by researchers as one of the most effective methods of artificial diamond formation. At the beginning of the XX century Russian researchers V. V. Digonsky, S. V. Digonsky, V. K. Garanin and others assumed that the electric discharge is the source of diamond formation in nature in the course of kimberlite "explosion pipes" formation. Since the early 70s two groups of researchers - in Tomsk, under the guidance of professor A. A. Vorobyov, and in Moscow consisted of two diamond geologists K. M. Alekseevsky and T. T. Nikolaeva, independently made the first steps in developing a new, electric discharge, hypothesis of kimberlite pipe formation. Results and conclusions. The convergence in the findings of two groups of independent researchers on electric discharge participation, on the one hand, in diamond formation, and on the other hand, in formation of kimberlite pipes should become a decisive factor in developing a new theory of diamond origin.
