About the book: 1959 / The appearance of Nefediev’s novel “The Mystery of the Diamond” is due to the fact that the USSR, after World War II and the beginning of the Cold War, was in dire need of diamonds and Significant funds were spent on exploration and the search for industrial methods for producing diamonds; At the same time, a lot of fiction and journalistic literature about diamonds appeared. Nefediev popularizes the industrial method of producing diamonds using a fantastic technique: he dates the discovery of the method of producing diamonds to 1917; its inventor found crystals of a substance at the site of the fall of the Tunguska meteorite, which served as a catalyst for the transformation of graphite into diamonds...
