Diamond Mining Research and Analysis - Page 3 of 4

The economics of diamond mining, how it works, the leading players involved in the industry, the issues they face, and the diamond value chain.

What Are the Forces Impacting Diamond Mining?

Above all, diamond mining is mostly impacted by consumer demand. Long-term shifts in interest as measured by how much consumers are willing to buy, the amount they are willing to spend, and the type of diamonds they are interested in all have an effect on diamond mining.

The impact of consumer demand may seem direct, however, the midstream – the manufacturing section of the diamond industry – often serves as a buffer between miners and consumers.

The following posts provide insights into exactly how this works, the ways miners sell rough diamonds, and the role mining plays in the economies of producing countries.

Who are the Largest Diamond Miners?

The leading miners by value are:

  1. De Beers

  2. ALROSA

  3. Rio Tinto

  4. Petra

  5. Dominion

Where are Diamond Mined?

  • The Russian Federation

  • Botswana

  • Canada

  • Australia

How Are Diamonds Mined?

  • Open pit

  • Alluvial

  • Underground

  • Marine
