05 april 2021 Today Almost every year, the Russian press reports on the future development of the Popigai deposit of impact diamonds in the north of the Krasnoyarsk Territory. These “sensations” have already grown more and more detailed, including the relevant agreements between the Siberian Branch of the Russian Academy of Sciences, the leadership of the Republic of Sakha (Yakutia), and the Krasnoyarsk Territory, as well as attracting ALROSA and AFK (Joint-Stock Financial Company) Sistema as investors, and even positioning this project as a joint one with the Republic of Belarus. According to the Popigai diamond proponents, they promise brilliant prospects to Russia and the world, they say that the development of the deposit will provide the world industry with new rough diamonds, the annual demand for which may rise to 1 billion carats. The public interest in the issue has been mounting and it inevitably requires answers to the questions - why has a unique diamond deposit discovered half a century ago turned out to be in no demand so far and what is the real prospect of its development taking into account the current state of the world diamond market?
