10 Top Diamond-producing Mines

- June 7th, 2017

Do you know where diamonds are produced? These 10 mines were the world’s top diamond-producing mines by output and value in 2016.

The story of the modern diamond market begins in 1871, when the De Beers and Kimberley mines were discovered in South Africa. That milestone helped De Beers, now owned by Anglo American (LSE:AAL), become the world’s largest diamond producer.
Despite some volatility in the market, global demand for diamonds has remained strong. According to Morgan Stanley (NYSE:MS), worldwide supply of rough diamonds is expected to expand to meet that demand between 2016 and 2021, driven by growth mainly in Canada and Russia. Overall, prospects for the market look bright.
But where are most diamonds being mined today? Read on for a brief overview of the world’s 10 top diamond-producing mines by output and value, based on 2016 data compiled by expert Paul Zimnisky. You can also click here to read about the five countries that produce the most industrial diamonds.
