- The first diamonds were discovered in ancient India around the 4th century B.C.
- Natural diamonds, often unearthed as rough diamonds, are the result of intense heat and pressure deep within the Earth, transforming carbon into these coveted gems.
- Currently, Russia is the leader in diamond production with around 40 millions carats per year.
- South Africa, with its well-known mines, plays a pivotal role in the diamond industry. However, diamond deposits scattered around the world contribute to the discovery of more diamonds, diversifying the sources of these precious stones.
- While large diamonds often capture global attention due to their rarity and value, many mines predominantly produce smaller stones, serving a vast segment of the jewelry market.
The Geology of Diamonds
Carbon is what diamonds are made of. When carbon atoms are subjected to immense pressure and temperatures ranging from 1,000 to 1,300°C, they crystallize to form diamonds. This transformation occurs at depths of about 150 to 200 kilometres beneath the Earth’s surface, within the thick, high-pressure layer known as the mantle. Here, the conditions are ripe for creating diamonds.
However, these gems don’t stay buried deep. A unique geological phenomenon brings them closer to the surface: volcanic eruptions. Unlike the lava-rich eruptions we commonly envision, the type that delivers diamonds is rare and particularly powerful. These eruptions force magma from the mantle at rapid speeds. As this magma ascends, it cools and solidifies to form carrot-shaped volcanic formations called kimberlite pipes.
Kimberlites are of immense interest to geologists and diamond miners alike. These pipes are composed of a mixture of minerals and, crucially, diamonds. They act as pathways, providing diamonds a route from their place of formation in the mantle to the Earth’s crust. Over millennia, erosion exposes sections of these pipes, making the diamonds within them accessible.
Where Exactly Are Diamonds Found? – A Comprehensive List of Diamond-Producing Countries
Ever since I became interested in the glint and gleam of diamonds, I’ve been equally intrigued by their origins. Going through the annals of diamond exploration, I’ve discovered that a select group of nations hold the honor of being the world’s gem-quality diamond producers. These leading diamond producers, with their rich geology and history of mining, are the heartbeats that find diamonds for the world’s commercial production of these sparkling gems. Let’s explore them below.
Russia, primarily through the diamond mining giant ALROSA, extensively mines diamonds in the expansive region of Yakutia. The Mir Diamond Mine, before its 2017 flooding, was an open pit reaching depths of about 525 meters, with plans to extend the underground portion to over 1,200 meters. The Udachnaya Pipe’s open-pit mining delved roughly 630 meters deep, while the Aikhal Underground Mine aims for depths around 200 meters, and the Botuobinskaya Open-Pit has operations that go down to about 200 meters.
Yakutia Region and Significant Mines
The heart of Russia’s natural gem-quality diamonds and its production pulses in the Yakutia region, also known as the Sakha Republic. Covering a staggering one-fifth of Russia’s landmass, this vast territory is a treasure trove of natural diamond mines, with chilling temperatures that ironically play host to the fiery brilliance of diamonds.
The Mirny diamond mine is particularly intriguing, a testament to Russia’s engineering prowess and tenacity. Dubbed the “Navel of the Earth,” this open pit mining is one of the deepest of its kind. It’s fascinating to think that what began as a small discovery in the 1950s by Soviet geologists has now morphed into a mining marvel.
Another standout in the Yakutia region is the Udachny mine. This mine, which translates to “Lucky” in Russian, lives up to its name. For decades, it has been a consistent contributor to Russia’s diamond output, producing millions of carats and serving as a beacon of the nation’s mineral wealth.
The Alrosa company emerged as a dominant name in the region’s diamond narrative. Responsible for the majority of Russia’s diamond extraction, Alrosa operates several mines in Yakutia and plays a pivotal role in positioning Russia as a heavyweight in the global diamond market.
The tales of Russian diamond mines paint a picture of resilience, innovation, and abundance. Russia, particularly the Yakutia region, isn’t just home to the Siberian cold; it’s also the cradle of gems that illuminate the world. According to Statista’s study of 2021, Russia’s diamond output reached over 39 million carats, witnessing a surge of approximately eight million carats from the prior year. The diamond yield in 2020 was the most modest since the recordings began in 2003. Following Botswana, Russia claimed the second-highest market valuation for diamond production globally in 2020.

The famous Argyle Diamond Mine
Nestled in the remote East Kimberley region of Western Australia, the Argyle Diamond Mine stands out not just as the country’s primary diamond producer, but also as one of the world’s most prolific sources of diamonds. What sets Argyle apart from other diamond mining sources globally is its abundance of pink diamonds, some of the rarest and most sought-after gems. These pink marvels, accounting for a significant chunk of the mine’s output, have made Argyle synonymous with luxury and rarity.
Since the start of its mining operations in 1983, Argyle has witnessed the extraction of over 800 million carats of diamonds. Though the mine primarily yields pink diamonds, it’s also a significant source of other color diamonds, including champagne, blue, and cognac hues. Such a diverse palette of gems has positioned Argyle as a unique entity in the global diamond market.
The Argyle diamond mine spans approximately 450,000 square meters or around 110 acres. Its layout extends mainly in a linear fashion for about 1,600 meters or 5,200 feet in length and varies in width from 150 to 600 meters or 500 to 2,000 feet. Constructed as an open pit, the mine’s greatest depth reaches roughly 600 meters or 1,900 feet.
In 2020, the mine ceased its operations, marking the end of an era. Its closure, however, has further fueled the allure of Argyle diamonds, as their scarcity now commands even higher premiums.
In essence, while Australia might not be the first name that springs to mind when one thinks of diamonds mined, the legacy of the Argyle Diamond Mine ensures that the nation holds a special place in the annals of diamond mining history.
Once a major rough diamond mining hub during the 17th century, Brazil’s alluvial deposits in the riverbeds were the world’s primary source of diamonds before the African diamond rush. Minas Gerais, a southeastern state, was particularly abundant in these gems. Though Brazil’s prominence in the diamond industry has diminished over time, overshadowed by African and Russian production, it still retains active mining areas. It plays a significant role in the global colored diamond market. Notably, Brazil’s deposits are often credited with a unique range of fancy-color diamonds, including rare hues of red and blue.
The majority of diamonds crystallized around 100 miles beneath the Earth’s surface. However, in the Brazilian region where Dr. Timmerman conducted his research, over 99% of diamonds are categorized as super-deep. These originate from the mantle’s transition zone, which lies between 254 and 410 miles deep.
Historically, India is the original home of diamond mining. The ancient Golconda region, now in modern-day Hyderabad, is famed for producing some of the world’s most legendary diamonds, including the Koh-i-Noor and the Hope Diamond. These mines were largely depleted by the 17th and 18th centuries, and while India’s contemporary contribution to the diamond industry revolves more around diamond cutting, polishing, and trading, the nation’s historical significance in the world of diamonds remains unmatched.
China is a relative newcomer to the diamond mining industry. Its history with diamonds, though brief, is impactful. The country saw its inaugural diamond manufacturing hubs in the 1980s, largely due to businesses shifting from Hong Kong to capitalize on China’s cost-effective labor. As the 1990s rolled in and China became increasingly accessible, diamond factories began setting up polishing units in burgeoning industrial zones, like Guangzhou, conveniently located near Hong Kong. Over time, the diversity of diamond products grew, and the craftsmanship significantly enhanced.
The nation’s primary deposits lie in the Liaoning Province, where diamond mining commenced in the 21st century. Though the quantity of genuine diamonds produced is modest compared to giants like Russia or Botswana, the quality, especially from the Changma Diamond Mine, is commendable. As China continues to grow its domestic diamond industry, there’s potential for increased production and global market influence.
In a nutshell, while countries like Botswana or Russia often dominate conversations about diamond mining, regions like Brazil, India, and China provide a rich tapestry of history, color, and diversity to global diamond consumption.
