Below are some of the leading diamond mines worldwide:
- Aikhal – Russia
Aikhal (means ‘fame’) is the biggest diamond mine in the world. It is in Yakutia, in the far east of Russia. The owner of this mine is one of the biggest mining companies in the world, Alrosa. ALROSA Group is a Russian partially state-owned diamond mining company. It accounts for a third of global rough diamond production. Aikhal started as an open pit from 1961 to 1997 and is from 2005 an underground mine with a depth of up to 200 meters and they are still going deeper. The annual production of the mine lies around 1.3 million carats and has reserves up to 40/50 million carats.
- Jwaneng – Botswana
Jwaneng (means ‘a place of small stones’) is the richest diamond mine in terms of value. It is located in the South of Botswana, in the Kalahari Desert. De Beers Group owns the diamond mine through a partnership with the government of Botswana. De Beers Group is the biggest mining company in the world, possessing 35% of global rough diamond production. Furthermore, Jwaneng is an open-pit mine and in use since 1982. The annual production lies around 12 million carats. As you can notice this is considerably more than the production of the Aikhal mine, value plays a big role.
- Udachny – Russia
Udachny (means ‘lucky’) is the third biggest diamond mine in the world and also located in Yakutia, like the Aikhal mine. Besides that, it is again part of the ALROSA Group. The diamond mine is an open-pit mine with a depth of more than 630 meters, which is considerably deep for an open-pit. The ALROSA group also started an underground mine as the open-pit mining resources are coming to an end. The annual production of the mine lies around 5 million carats due to the underground mine.
- Nyurba – Russia
Nyurba is again located in Yakutia. The ALROSA Group owns this diamond mine, but the Nyurba Mining and Processing Division, a subsidiary company of the ALROSA group operates it. Nyurba is an open-pit mine since 2001 but only began its productions in 2015. This makes it one of the youngest mining and processing divisions of the ALROSA group. The diamond output varies quite a lot, in a range between 0.7 and 2 million carats per year.
- Orapa – Botswana
The Orapa (means ‘resting place for lions’) mine is named after the city it is located in, in the East of Botswana. De Beers Group owns the diamond mine through a partnership with the government of Botswana, just like the Jwaneng mine. Orapa is an open-pit mine and begun its productions in 1971. It has an annual production of around 11 million carats. They had a record of 17.3 million carats of diamonds in 2006! A new town was built to support this mine.
- Catoca – Angola
The Catoca diamond mine is located in the Northeast of Angola. The African diamond mine is the sixth largest diamond mine in the world. It is owned through a joint venture of Endiama (32.8%), The ALROSA Group (32.8%), China Sonagol (18%), and Odebrecht Mining (16.4%). The Catoca is an open-pit mine and began productions in 1997. Its normal annual output is around 10 million carats, but they had a downfall in 2020 of 80%. The annual output was only 2 million carats. This mine accounts for 75% of Angola’s total diamond production, so it was not a good year for Angol.
- Lomonosov – Russia
The Lomonosov (named after a Russian scientist) diamond mine is located in the Northwest of Russia, in Arkhangelsk Oblast near Europe. Lomosonov is owned by the ALROSA group and operated by a subsidiary of ALROSA, namely PAO Sevarlmaz. The mine’s annual production is around 2 million carats. One in every 350 carats of this mine is fancy colored. That is quite an impressive amount.
- Mir – Russia
Mir means peace in Russian. This diamond mine is again part of the ALROSA Group but the Mirny mining and processing division owns and operates the diamond mine. The production of the open-pit mine started in 1957 and stopped in 2001. Underground mining began in 2009 but unfortunately stopped in 2017 and it never started again. There is a chance they will resume productions starting from 2030 on. Annual production was at around 3 million carats.
