Experimental models of natural synthesis of diamond polycrystals are considered in the following systems: hydrocarbon–graphite, metal–graphite. Within the scope of the theory of percolation and symmetry approach to crystallogenetic process on the basis of the theory of potential energy, the structure and mechanisms of diamond-aggregates formation are explained. As revealed, the various nanosized carbon species (spherical and coalesced onion-like carbon particles, faceted polyhedral particles, graphitic ribbons, graphitic folds, and nanocrystalline diamonds) are present in the conversion products together with micron-size crystallites of graphite and diamond.
