Before a natural diamond reaches a jewellery store, it begins its journey deep within the Earth.
Natural diamonds form under extreme heat and pressure over geological timescales. They are eventually brought closer to the Earth’s surface through volcanic activity and can be recovered from kimberlite pipes, alluvial deposits and even the seabed.
Today, major diamond mines in the world are found across Botswana, Russia, Angola, Canada, South Africa and Lesotho.
From mines producing millions of carats to legendary locations known for enormous or rare coloured diamonds, here are 15 of the world’s most famous diamond mines.
Note: This list considers global importance, production history, famous discoveries and significance to the natural diamond industry. It is not a strict ranking by annual production or reserves.

Known for: One of Angola’s major new diamond projects
Luele represents a newer chapter in African diamond mining.
Located in Angola’s diamond-rich Lunda region, the deposit has become increasingly important as the country expands its natural diamond production.
Its development also shows how the geography of global diamond supply continues to evolve beyond long-established mines.
6. Cullinan Diamond Mine, South Africa
Location: South Africa
Known for: The world’s largest gem-quality rough diamond
Few diamond mines have produced a discovery as famous as Cullinan.
In 1905, the mine produced the legendary Cullinan Diamond, weighing approximately 3,106 carats in its rough form.
It remains the largest gem-quality rough diamond ever discovered.
Cullinan is also famous for rare blue diamonds and exceptional Type II diamonds and continues to be an important South African mine.
7. Venetia Diamond Mine, South Africa
Location: Limpopo, South Africa
Known for: Major modern South African diamond production
Venetia is one of South Africa’s most important modern diamond mines.
The operation has been transitioning from open-pit to underground mining, with underground production beginning in 2023.
De Beers reported strong underground production during the first half of 2026, although it has proposed a two-year production pause beginning in the second half of 2026 as part of changes responding to diamond-market conditions.
8. Letšeng Diamond Mine, Lesotho
Location: Lesotho
Known for: Large, high-quality white diamonds
Located high in the mountains of Lesotho, Letšeng has built a reputation for producing exceptional large diamonds.
Gem Diamonds describes Letšeng as the highest average dollar-per-carat kimberlite diamond mine in the world.
The mine continues to produce notable stones. In June 2026, it recovered an exceptional 346.99-carat Type II white diamond.
9. Gahcho Kué Diamond Mine, Canada
Location: Northwest Territories, Canada
Known for: Major Canadian diamond production
Gahcho Kué is one of Canada’s important operating diamond mines.
Located in the remote Northwest Territories, it is jointly owned by De Beers and Mountain Province Diamonds.
Production increased strongly during the first half of 2026 as higher-grade ore from a new mining area was processed.
10. Ekati Diamond Mine, Canada
Location: Northwest Territories, Canada
Known for: Canada’s first major diamond mine
Ekati transformed Canadian diamond history when commercial production began in 1998.
It became Canada’s first major diamond mine and helped prove that the country’s remote northern region contained commercially important diamond deposits.
Its current mine plan runs to around 2028, while further projects could potentially extend mining considerably longer.
11. Diavik Diamond Mine, Canada
Location: Northwest Territories, Canada
Known for: More than 150 million carats produced
Diavik was one of Canada’s most significant diamond mines.
But unlike many older lists of famous diamond mines, Diavik should now be described as a closed mine.
After 23 years of operations and more than 150 million carats of rough diamonds, Diavik produced its final diamonds in March 2026.
Its closure marks the end of an important chapter in Canadian diamond mining.
12. Aikhal Diamond Mine, Russia
Location: Yakutia, Russia
Known for: Major Russian diamond production
Aikhal is part of Russia’s enormous diamond-mining industry in Yakutia.
The region contains several important kimberlite deposits and has helped make Russia one of the world’s largest natural diamond producers.
ALROSA lists Aikhal as an underground operation with a target production capacity of approximately 3 million carats annually.
13. Udachny Diamond Mine, Russia
Location: Yakutia, Russia

Location: Mirny, Russia
Known for: Its enormous open pit
The Mir Mine is one of the most visually recognisable diamond mines ever created.
Its huge open pit became an icon of Russian diamond mining.
Mining at the original Mir pipe was suspended following an accident in 2017, and the deposit remains under conservation while future underground development is considered.
ALROSA’s long-term strategy includes the proposed Mir-Gluboky underground project, with production currently targeted for 2034.
15. Argyle Diamond Mine, Australia
Location: Western Australia
Known for: Rare pink diamonds
Argyle changed the global coloured-diamond market.
The mine became world-famous for its distinctive pink, red and purple diamonds, some of which rank among the rarest coloured diamonds in the world.
Argyle produced more than 865 million carats of rough diamonds during approximately 37 years of operations.
However, it is important to note that Argyle is no longer an operating diamond mine. Mining ended in November 2020.
Its pink diamonds continue to make Argyle one of the most famous names in diamond history.
What About Diamond Mines in India?
India has an extraordinary place in diamond history.
For centuries, the Indian subcontinent was the world’s principal known source of diamonds, with historic mining regions producing stones that eventually entered royal collections around the world.
Today, India’s modern diamond-mining activity is much smaller.
The country’s best-known modern diamond mine is the Majhgawan Diamond Mine near Panna in Madhya Pradesh.
India may no longer be one of the world’s largest diamond-mining countries, but it remains deeply important to the global diamond story, particularly through its modern diamond cutting and polishing industry.
How Are Diamonds Mined?
Not every diamond is recovered in the same way.
The main methods include:
Open-pit mining: Diamond-bearing rock is extracted from large surface excavations.
Underground mining: Tunnels and shafts are used to reach deeper diamond-bearing ore.
Alluvial mining: Diamonds that have been transported by rivers are recovered from sediments and gravel.
Marine mining: Diamond-bearing material is recovered from the seabed, particularly along parts of the southern African coastline.
Once recovered, rough diamonds are sorted before entering the cutting, polishing and jewellery manufacturing process.
From Diamond Mine to IDT Certification
The mine may tell us where the journey of a natural diamond began, but it does not tell us everything about the polished diamond in front of us.
Diamonds from the same mine can differ significantly in carat weight, colour, clarity, proportions and other characteristics.
Today’s jewellery market also includes both natural and laboratory-grown diamonds, which can appear extremely similar to the unaided eye.
This is where professional gemological testing becomes important.
At IDT Gemological Laboratories Worldwide, diamonds are examined using gemological testing and advanced analytical methods. Depending on the type of report, an IDT Diamond Report can provide important information including:
- Natural or laboratory-grown identification
- Carat weight
- Colour
- Clarity
- Measurements and proportions
- Fluorescence
- Other identifying characteristics
A diamond’s mine may be part of its origin story.
IDT Certification helps you understand the diamond itself.
Always insist on IDT Certification.
