Today the majority of diamonds are produced in four main regions. Which are they?

• A. Eurasia, North America, Australia, and Africa
• B. Asia, Europe, North America, and Africa
• C. Eurasia, Africa, North America, and Australia
• D. Eurasia, Australia, Africa, and Antarctica

Answer: (A)

Diamonds today come from four broad regions: Eurasia, North America, Australia, and Africa. This grouping reflects where the largest, long-standing diamond mining operations and reserves are found. In Eurasia, Russia sits among the top producers with extensive kimberlite fields in Siberia and surrounding areas. North America’s diamond supply is dominated by Canada, with major mines in the north that rely on advanced, year-round mining and processing. Australia remains a key region, historically known for its prolific diamond-bearing deposits in Western Australia. Africa has long been a diamond powerhouse, with Botswana, Namibia, South Africa, and Angola contributing substantial volumes.

This distribution makes sense because it aligns with geological settings that host sizable diamond-bearing rocks and the development of robust mining infrastructure in those areas. The other regions listed, like Antarctica, do not have active diamond production, and splitting Eurasia into Asia or Europe alone would omit Canada or Russia’s contribution, which is why the four-region grouping given is the best fit.
