Which statement about profitable diamond sources is true?

• A. They are common
• B. They are uncertain
• C. They are abundant
• D. They are rare

Answer: (D)

Profitability in diamond mining hinges on scarcity combined with the costs of extraction and processing. Diamonds command high prices precisely because high-quality, gem-grade deposits are uncommon. If profitable sources were common or abundant, supply would grow faster than demand, prices would drop, and profits would vanish. While exploration involves risk, there are very few deposits that meet the economic thresholds to be truly profitable, so the fact that profitable sources are rare best fits how the industry actually behaves.
