| Summary: | The history of the discovery of diamonds in the products of Kamchatka volcanic eruptions is briefly described, and the results of comprehensive studies of Tolbachin diamonds including crystallomorphology, faceted sculptures, xenomineral greases and films on the surface, nanomicroswitches, impurity elements, spectroscopic properties, isotopic composition of carbon and nitrogen are summarized. The conclusion is drawn about the natural origin of the Tolbachin diamonds formed directly in the volcanic ash-gas cloud by crystallization from gases stimulated by atmospheric electric discharges. |
