How Diamonds Are Mined (in Russia)

Posted on May 20, 2014 by tim

Diamonds were formed more than 300 million years ago. Kimberlite magma formed at a depth of 20 or 25 km. Magma gradually rises along faults in the crust and when the upper layer can no longer hold back the pressure of the magma, an eruption occurs. The first such “pipes” were found in Kimberley inSouth Africa and from there came the name. In the mid 50s rich primary diamond deposits were discovered in Yakutia. Here the diamonds were found in about 1500 kimberlite pipes.

The Russian company “ALROSA” produces 99% of diamonds in Russia and more than 25% of the diamonds in the world .

The kimberlite pipe “Mir” (Peace) is an indigenous diamond mine that had been opened in 1955. The field was developed initially at Mirny where an open pit mine and processing plant were created. The quarry has a depth of 525 m and a diameter of 1.2 km, so it is one of the largest in the world. Diamondiferous kimberlite ore open pit mining ceased in June 2001. Since 2009, mining diamond ore is done in the “Mir” underground mine.

City of Mirny – the diamond “capital” of Russia, located in Yakutia. It is 1200 km from Yakutsk.

The population is 35000 people.

Lenin’s Square is the center of the city.

The Airport.

The headquarters of Russia’s largest diamond company “ALROSA” is also situated in Mirny.
The company started with a trust called “Yakutalmaz”, formed for the development of indigenous diamond deposits in Yakutia in the early 1950s.

The quarry is located close to Mirny.

    Diamonds are common pebbles. The only reason I would buy one is if I needed something hard to cut with.
    Want to buy your girlfriend something nice, get something rare, diamonds are only pretty.
    DeBeers diamond cartel, has vaults filled with diamonds they’re keeping off the market to keep the price high. Eventually the price will bottom out and that “pretty stone” you paid thousand of dollars for, will be worth just dollars.
    When Diamonds were discovered in Russia a while back, DeBeers absolutely freaked out. They bought as much as they could, but finally stopped. Then the mines in Canada did the same thing to them.
    They can’t keep enough off the market.

      Pretty hypocritical post to call diamonds common pebbles and then act all high and mighty about “rare” items. What the hell is that supposed to mean anyway? Does a girl really want some POS she doesnt care about and cant wear on her finger? Your precious “rare” items are probably made from threads and plastic anyway…aka more superficial, material BS you cant take with you. Keep your rare items and I will keep getting beautiful diamonds for my beautiful girl.

        I think George was just trying to explain that Debeers has a monopoly over the global supply of diamonds hence the inflated price.
        As a a 2nd year geology student, there are many rarer naturally occurring minerals than diamond that have a price tag to match.
        However from advertisements and songs such as “diamonds are a girls best friend” etc, a rarer mineral may not be well received from a social perspective in the place of the more common diamond- A completely different issue.
