Top Ten Diamond-Producing Countries

De Beers has been synonymous with diamonds due to their
 domination of mining and selling over the past 100 years. De Beers controlled
 the prices and distribution of diamonds worldwide until 2000, when their
 control on diamonds began to break. Diamond producers from Russia, Canada, and
 Australia decided to sell directly to manufacturers without going through De
 Beers as a middleman. This paved the way for diamond mining companies to become
 key players; however, De Beers remains the undisputed diamond mining and
 manufacturing leader.

De Beers also owns the Diamond Trading Company, which sells
 and distributes rough diamonds, and De Beers Diamond Jewelers Ltd., which it
 co-owns with the famous brand Louis Vuitton Moët Hennessy Group (LVMH). De
 Beers sells its diamonds through LVMH after having them polished and set into
 jewelry. In several countries in Africa, De Beers co-owns diamond mines through
 deals with the government.

ALROSA is one of the few companies close to being a
 competitor to De Beers, with their discovery of the Verhne-Munskoye mine in
 2007. The company currently operates 16 kimberlite pipes and 16 alluvial mines.
 It also has operations in nine countries and ten regions in Russia. The company
 accounts for over 25% of the world's diamond carat output. 95% of Russia's
 total diamond production is done through ALROSA.

From ALROSA's mines, preliminary sorting and valuation of
 the mined diamonds are first undertaken in their Diamond Sorting Center in
 Mirny. The initial valuation of these diamonds takes place in three locations:
 at ALROSA's United Selling Organization in Moscow, the Kommeral Company in
 Mirny, and at Yakutsk Diamond Trading Enterprise in Yakutsk. The smallest
 diamonds mined are separated at the preliminary sorting and sent to the
 Kommeral Company, where they are sold as industrial diamonds or manufactured into
 diamond powder.

<a href="https://www.petragems.com/rio-tinto/">Rio Tinto
 Group</a> is another major diamond producer. It has been in the industry since
 1979 and operates two diamond mines in Australia and Canada while also
 developing another mine in India. Rio Tinto used to operate the Murowa Diamond
 Mine near Zvishavane in Zimbabwe until 2015, when it sold its shares to a
 Zimbabwean mining company.

Rio Tinto primarily deals in mining, selling, and marketing,
 mostly rough or uncut diamonds. It is also known for the Argyle pink diamonds
 mined from Western Australia. Most of the diamonds from this mine are cut and
 polished for jewelry purposes. The rare pink Argyle diamond is primarily
 sourced from this mine and has become the trademark stone of the company. Their
 second mine, Diavik mine in the Northwest Territories in Canada, produces some
 of the most coveted high-grade diamonds in the world, possessing good shape and
 great clarity. The diamonds mined in Rio's facilities are sorted in Antwerp,
 Belgium, and sent to Perth, Australia, where they are cut and polished. The
 polished stones are then sold in the US, Hong Kong, and Indian diamond markets.

<a href="https://www.petragems.com/debswana/">Debswana
 Diamond Company</a> Ltd. is the world's leading diamond-producing company in
 terms of value and the second-largest in terms of volume. It is a Botswanan
 company operating four mines in Orapa, Jwaneng, Lethalkane, and Damtshaa. It is
 co-owned by the Botswana government and the De Beers Group. Debswana has been
 instrumental in uplifting the economy of Botswana, helping it rise from being
 one of Africa's poorest to its current status as a middle-income nation.

Diamonds mined in the Orapa and Jwaneng sites are sorted in
 state-of-the-art facilities inside the mining compounds. Similar facilities are
 already being installed in all of Debswana's other mines.

Diamonds produced by Debswana
 are sold through the Diamond Trading Company of De Beers. De Beers sells them
 to clients at events called “sights” held in Gaborone.

The <a href="https://www.petragems.com/dominion-diamond-corporation-mines-ekati-and-diavik/">Dominion
 Diamond Corporation</a> (DDC) is a Canadian company operating two mines in
 Diavik and Ekati. DDC was formerly known as the Harry Winston Diamond
 Corporation, which was completely bought by Aber Diamond Corporation in 2006.
 This eventually became the Dominion Diamond Corporation that it is today.

DDC's mines in Diavik are co-operated with the Rio Tinto
 Group, although DDC has sole mine ownership. Its diamonds are sent to its
 sorting facilities in Toronto to be sorted according to clarity, color, weight,
 and shape. They are then shipped to the Antwerp and Mumbai sales offices, where
 up to 75% of their diamonds are put up for sale on the open market. One of
 DDC's famous clients is Tiffany &amp; Co, America's premier jewelry house. DDC
 is the world's third-biggest provider of rough diamonds in terms of value.

Leading Diamond Companies in the World

The city of Antwerp in Belgium is the world's trading center
 for diamonds. It is home to over 1,500 diamond companies, including rough
 diamond traders, manufacturers, dealers, and sellers of polished diamonds. An
 estimated 80% of the total rough diamonds in the world are handled in this
 city, which accounts for €30 billion of its annual income. This is why Antwerp
 is known as the Diamond capital of the world.

Although Antwerp mostly controls the production and
 marketing of diamonds, there are also large diamond trading centers in the
 Indian cities of Surat and Mumbai. Israel is also a trade center, mainly
 supplying diamonds to North America. In the Middle East, Dubai is the region’s
 distribution hub. In the US, <a href="https://www.petragems.com/buy-diamonds-in-new-york/">New York</a> remains
 the primary port where diamonds are brought into the country and is currently
 the largest diamond market in the world. It is where an estimated 80% of the
 diamonds worldwide are sold.
