Ranked: World Diamond Mining By Country, Carat, and Value

Only 22 countries in the world engage in rough diamond production—also known as uncut, raw or natural diamonds—mining for them from deposits within their territories.

This chart, by Sam Parker illustrates the leaders in rough diamond production by weight and value. It uses data from Kimberly Process (an international certification organization) along with estimates by Dr. Ashok Damarupurshad, a precious metals and diamond specialist in South Africa.

Rough Diamond Production, By Weight

Russia takes the top spot as the world’s largest rough diamond producer, mining close to 42 million carats in 2022, well ahead of its peers.

ℹ️ Carat is the unit of measurement for the physical weight of diamonds. One carat equals 0.200 grams, which means it takes over 2,265 carats to equal 1 pound.

Russia’s large lead over second-place Botswana (24.8 million carats) and third-ranked Canada (16.2 million carats) indicates that the country’s diamond production is circumventing sanctions due to the difficulties in tracing a diamond’s origin.

Here’s a quick breakdown of rough diamond production in the world.

As with most other resources, (oil, gold, uranium), rough diamond production is distributed unequally. The top 10 rough diamond producing countries by weight account for 99.2% of all rough diamonds mined in 2022.

Diamond Mining, by Country

However, higher carat mined doesn’t necessarily mean better value for the diamond. Other factors like the cut, color, and clarity also influence a diamond’s value.

Here’s a quick breakdown of diamond production by value (USD) in 2022.

22🇲🇱 Mali$0.06M

Note: South Africa’s figures are estimated. Furthermore, numbers have been rounded and may not sum to the total.

Thus, even though Botswana only produced 59% of Russia’s diamond weight in 2022, it had a trade value of nearly $5 billion, approximately 1.5 times higher than Russia’s for the same year.

Another example is Angola, which is ranked 6th in diamond production, but 3rd in diamond value.

Both countries (as well as South Africa, Canada, and Namibia) produce gem-quality rough diamonds versus countries like Russia and the DRC whose diamonds are produced mainly for industrial use.

Which Regions Produce the Most Diamonds in 2022?

Unsurprisingly, Africa is the largest rough diamond producing region, accounting for 51% of output by weight, and 66% by value.

RankRegionShare of Rough
Diamond Production (%)
Share of Rough
Diamond Value (%)
1Africa51.4%66.4%
2Europe34.9%32.9%
3North America13.5%52.8%
4South America0.2%2.4%

However diamond mining in Africa is a relatively recent phenomenon, fewer than 200 years old. Diamonds had been discovered—and prized—as far back as 2,000 years ago in India, later on spreading west to Egyptian pharaohs and the Roman Empire.

By the start of the 20th century, diamond production on a large scale took off: first in South Africa, and decades later in other African countries. In fact between 1889–1959, Africa produced 98% of the world’s diamonds.

And in the latter half of the 20th century, the term blood diamond evolved from diamonds mined in African conflict zones used to finance insurgency or crime.

Strategic Metals

The Critical Minerals to China, EU, and U.S. National Security

Ten materials, including cobalt, lithium, graphite, and rare earths, are deemed critical by all three.

The Critical Minerals to China, EU, and U.S. Security

Governments formulate lists of critical minerals according to their industrial requirements and strategic evaluations of supply risks.

Over the last decade, minerals like nickel, copper, and lithium have been on these lists and deemed essential for clean technologies like EV batteries and solar and wind power.

This graphic uses IRENA and the U.S. Department of Energy data to identify which minerals are essential to China, the United States, and the European Union.

What are Critical Minerals?

There is no universally accepted definition of critical minerals. Countries and regions maintain lists that mirror current technology requirements and supply and demand dynamics, among other factors.

These lists are also constantly changing. For example, the EU’s first critical minerals list in 2011 featured only 14 raw materials. In contrast, the 2023 version identified 34 raw materials as critical.

One thing countries share, however, is the concern that a lack of minerals could slow down the energy transition.

The Critical Minerals to China, EU, and U.S. Security

With most countries committed to reducing greenhouse gas emissions, the total mineral demand from clean energy technologies is expected to double by 2040.

U.S. and EU Seek to Reduce Import Reliance on Critical Minerals

Ten materials feature on critical material lists of both the U.S., the EU, and China, including cobalt, lithium, graphite, and rare earths.

Despite having most of the same materials found in the U.S. or China’s list, the European list is the only one to include phosphate rock. The region has limited phosphate resources (only produced in Finland) and largely depends on imports of the material essential for manufacturing fertilizers.

Coking coal is also only on the EU list. The material is used in the manufacture of pig iron and steel. Production is currently dominated by China (58%), followed by Australia (17%), Russia (7%), and the U.S. (7%).

The U.S. has also sought to reduce its reliance on imports. Today, the country is 100% import-dependent on manganese and graphite and 76% on cobalt.

After decades of sourcing materials from other countries, the U.S. local production of raw materials has become extremely limited. For instance, there is only one operating nickel mine (primary) in the country, the Eagle Mine in Michigan. Likewise, the country only hosts one lithium source in Nevada, the Silver Peak Mine.

China’s Dominance

Despite being the world’s biggest carbon polluter, China is the largest producer of most of the world’s critical minerals for the green revolution.

China produces 60% of all rare earth elements used as components in high-technology devices, including smartphones and computers. The country also has a 13% share of the lithium production market. In addition, it refines around 35% of the world’s nickel, 58% of lithium, and 70% of cobalt.

Among some of the unique materials on China’s list is gold. Although gold is used on a smaller scale in technology, China has sought gold for economic and geopolitical factors, mainly to diversify its foreign exchange reserves, which rely heavily on the U.S. dollar.

Analysts estimate China has bought a record 400 tonnes of gold in recent years.

China has also slated uranium as a critical mineral. The Chinese government has stated it intends to become self-sufficient in nuclear power plant capacity and fuel production for those plants.

According to the World Nuclear Association, China aims to produce one-third of its uranium domestically.
