The Mirny mine is one of the largest open-pit mines in the world, located in the remote town of Mirny in the Sakha Republic of Russia. The mine was discovered in the 1950s, and its construction began in 1957, lasting until 1960. The mine has a depth of over 1700 feet and a diameter of 3900 feet, making it the second deepest excavated hole in the world.

Discovery of the Mine

The Mirny mine was discovered during the Soviet era by a geologist named Yuri Khabardin in 1955. At the time, the Soviet Union was looking to expand its diamond production, and Khabardin’s discovery was a significant breakthrough. The area around the mine was uninhabited and covered in permafrost, making the construction of the mine a daunting task.

The construction of the Mirny mine was a challenging task that required cutting through layers of permafrost and bedrock. The construction crew used a variety of heavy machinery, including bulldozers, cranes, and trucks, to remove the overlying soil and create the mine’s distinctive funnel shape. The mine’s construction required the excavation of over 22 million cubic meters of earth.

Mining Operations at the Mirny Diamond Mine

The Mirny mine has been operational since 1960, and it has been a significant producer of diamonds since then. The mine produces both industrial and gem-quality diamonds, with the gem-quality stones being particularly notable for their size and clarity. The mine’s output is sorted and processed at nearby factories before being sold to diamond traders and dealers.

Environmental Impact of the Mirny diamond Mine

The construction and operation of the Mirny mine have had a significant impact on the local environment. The removal of large amounts of earth and the use of heavy machinery have caused soil erosion, air pollution, and noise pollution in the area. Additionally, the mine has disrupted the local ecosystem, displacing wildlife and altering the local hydrology.

Significance of the Mirny Diamond Mine

The Mirny mine has been a significant contributor to the global diamond industry, producing some of the world’s most valuable and famous diamonds. The mine’s output has included the 3106-carat Cullinan diamond, the largest gem-quality diamond ever found, as well as the 342-carat Tereshchenko diamond and the 171-carat Jubilee diamond. The mine has also been a significant source of employment and economic development in the region.


The Mirny mine is a remarkable feat of engineering and a significant contributor to the global diamond industry. The mine’s discovery, construction, and operation have had a significant impact on the local environment and economy, as well as on the wider world of diamonds. The mine’s legacy will continue to be felt for many years to come.

  1. This place mines soooo many diamonds that the Russians were going to crash the world market. Diamonds are not scarce it’s a “myth” propagated by the Oppenheimer Family (aka. De Beers) going back to when diamonds were discovered on the beach in Namibia the size of coconuts. Oppenheimer’s laid a claim in prospecting rights in Namibia (and won) and got nauseatingly rich. Consequently bought De Beers with their incredible wealth. The rest is market control monopoly.

    The Oppenheimers got the Russians to agree for De Beers to be the sole distributor/suppliers and thereby continue the false scarcity market and myth. Win win for Russians (billions of $$$) and Oppenheimer’s continue to rule the world market in diamonds.

    “Diamonds are a girls best friend” and “Diamonds are forever” are straplines invented by De Beers 😳 💰💰💰
