Analyzing the magnetotransport data obtained on nanocrystalline variety of heavily boron-doped diamond, we have proposed a new model of unconventional superconductivity in this material based on the very experimental fact that the symptoms of localization are precursors of superconducting transition. It is shown by quantitative arguments that the system treated as disordered Mott's metal in which the transport is controlled by weak localization of carriers should reveal, in the Kelvin range, superconducting transition just when the holes occupying neighbouring weakly localized orbits are paired by means of a spin-flip mechanism.
