RANKED: World’s richest diamond mines
The diamond industry was one of the winners as the world economy rebounded from the effects of the pandemic. Consumer demand for diamond jewelry grew last year, while supply remained constrained.
This year, the $80 billion industry saw more turmoil as cutters, polishers and traders hunted for ways to keep buying from Russia — Russian miner Alrosa accounts for about a third of global rough-diamond supply. The sudden shortage of stones sent diamond prices surging, but Alrosa PJSC has revived exports to near pre-war levels.
Using data compiled by Mining Intelligence, the latest top ten list ranks the world’s biggest diamond mines, delineated by carat production for Q1-Q3 2022 (kct) (chart 1) and estimated value (USD million) during this period (chart 2). The estimated value is based on average historic annualized price per carat.
Production:
#1 Jwaneng
Jwaneng, which means “a place of small stones” tops our list for production with 10,319 kct. Located in the Naledi River Valley of southern Botswana, the Jwaneng pipe was first discovered in 1972, and became fully operational a decade later. The Jwaneng mine falls under the Anglo American portfolio operated by Debswana, a partnership between the De Beers company and the government of Botswana. Debswana has earmarked $6 billion to build the world’s largest underground diamond mine at Jwaneng, already the richest diamond mine in the world.
#2 Orapa
One of four Debswana operations in Botswana, Orapa, meaning “resting place for lions”, is the world’s largest diamond mine measured by area and number 2 on our list with 8,033 kct. The mine was discovered in 1967 by a team of De Beers Geologists led by Manfred Marx. It became fully operational in 1971. Currently, Orapa is mining at a depth of 305 metres and is expected to reach 350 metres by 2026.
#3 Udachny
The biggest diamond mine owned by Alrosa, Udachny ranked number 3 with 4,649 kct. Udachny is located in the Sakha Republic region of Russia, just outside the Arctic circle. Discovered in 1955, the first stage of mining and processing complex was commissioned in 1976. At a depth of more than 630 metres, Udachny is currently the third deepest open-pit mine in the world (after Bingham Canyon Mine and Chuquicamata).
#4 Venetia
Anglo American’s Venetia mine in South Africa is number 4, producing 4,567 kct. Venetia mine was designed as an open pit, and in 2013, an underground extension project began with plans to ramp up to full production by 2025 while extending the mine life to 2046.
#5 Nyurba
Alrosa’s Nyurba mine in Yakutia, Russia is number 5 on our list, producing 3,616 kct. in 2019, Alrosa found a Matryoshka-style stone in Nyurba, the first in diamond mining history.
Value:
#1 Jwaneng
Jwaneng is also the richest diamond mine in the world in terms of value, estimated at $1.25 billion, with an average historic annualized price at $121.5 per carat.
#2 Orapa
Orapa holds second place for value as well, estimated at $976 million, and neck and neck with Jwaneng with an average historic annualized price at $121.5 per carat.
#3 Venetia
Venetia swapped 4th place in production for third place in value, estimated at $425 million and an average historic annualized price at $93 per carat.
#4 Udachny
Udachny, number 3 for production, ranked number 4 for value, estimated at $404 million and with an average historic annualized price at $87 per carat.
#5 Diavik
Canada’s Diavik mine, owned by Rio Tinto, makes an appearance as number 5 in terms of value, estimated at $394 million and with an average historic annualized price at $118.2 per carat.
