The largest percentage of world diamond production by weight is mined in which country?

The largest percentage of world diamond production by weight is mined in which country?

• A. India
• B. Russia
• C. Australia
• D. Canada

Answer: (C)

The key idea is that the country with the most diamond production by weight is the one that yields the largest volume of carats from its mines each year. Australia stands out here because its diamond districts in Western Australia have supported long-running, high-volume production from major pipe mines and associated deposits. That combination—big, sustained output—pushes Australia’s annual carat totals to lead global weight share in many datasets. Other countries produce diamonds as well, but their annual carat tonnage is typically smaller in comparison to Australia’s high-volume operations, which is why they don’t reach the same weight share.
