Kimberlite pipe “Nyrbinskaya”
A kimberlite pipe is a remnant of very ancient volcanic activity. The volcano’s cone no longer exists; only the underground part remains, an almost vertical cone (the pipe) filled with lava that solidified long ago. In 2013, mining at the deposit had reached an approximate depth of 255 meters. In 2015, a 179-carat diamond called “Romanov” was found here. 🐻
