What is the primary sales channel for rough diamonds?

• A. Auctions
• B. Long-term contracts
• C. Spot market
• D. Online trading

Answer: (B)

Long-term contracts are the main way rough diamonds move from miners to manufacturers. This setup provides steady supply and predictable pricing, which is crucial for planning cutting, polishing, and financing downstream. Producers commit volumes and terms over years, and buyers gain reliable access to rough they need for production pipelines. Auctions and the spot market do occur, especially for excess or opportunistic lots, but they handle a smaller portion of total rough volume and are more volatile. Online trading exists but is not yet the dominant channel compared with traditional contract-based sales.
