Diamond Mines in the World

Located in the north-western part of Russia , Grib is an open-pit diamond mine estimated to contain over 98 million carats . The mine is expected to become the largest diamond mine in Russia in terms of size . The Grib mine is owned and operated by Lukoil through its subsidiary Arkhangelskgeoldobycha ( AGD ). With production commencing in June 2013 , the site is planned to go underground after 16 years of openpit operation . Grib is the first new non-alluvial diamond mine to produce more than one million carats per year .
