Which mine's production was noted for influencing the world market in the late 1980s?

• A. Venetia
• B. Diavik
• C. Argyle
• D. Letseng

Answer: (C)

Market impact comes from the size of a mine’s output. When a mine produces a large share of the world’s diamonds, its production levels can shift overall supply, influencing prices and market trends. Argyle fit that role in the late 1980s. Located in Australia, its substantial rough-diamond production—spanning a broad range of stones, including colored varieties—made it a dominant source in global supply, so changes in Argyle’s output helped shape the world market then. Venetia and Letseng produced important gems, but their combined output didn’t match Argyle’s scale during that period, and Diavik wasn’t operating yet in the late 1980s.
