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.

Note: South Africa’s figures are estimated.

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.

1🇧🇼 Botswana$4,975M
2🇷🇺 Russia$3,553M
3🇦🇴 Angola$1,965M

21🇻🇪 Venezuela$0.10M
22🇲🇱 Mali$0.06M
Total$16,290M

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 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.

Charted: The End-of-Life Recycling Rates of Select Metals

End-of-life recycling rates measure the percentage of a material that is recovered at the end of its useful life, rather than being disposed of or incinerated.

We visualize the end-of-life recycling rates (EOL-RR) of commonly used metals in the economy. Data is sourced from the International Energy Agency, last updated in 2021.

ℹ️ EOL-RR is the percentage of a material or product that is recycled or recovered at the end of its useful life, rather than being disposed of in landfills or incinerated.

Tracking recycling rates helps manage resources better and make smarter policies, guiding efforts to cut down on waste.

Ranked: The End of Life Recycling Rates of Select Metals

Gold has an 86% recycling rate according to the latest available data. Per the Boston Consulting Group, one-third of total gold supply was met through recycling between 1995–2014.

Note: Figures are rounded.

Several factors can influence metal recycling rates. According to this International Resource Panel report, metals that are used in large quantities (steel) or have a high value (gold) tend to have higher recycling rates.

However, for materials used in small quantities in complex products (REEs in electronics), recycling becomes far more challenging.

Finally, a metal’s EOL-RR is strongly influenced by the least efficient link in the recycling chain, which is typically how it’s initially collected.
