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.

Other Locations

Beyond the famed diamond strongholds of Botswana, Russia, and Canada, several other regions around the world hold hidden caches of these sparkling treasures. Let’s explore what other locations have diamond mining companies.

Brazil

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.

India

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

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.
