What characterizes the downstream phase of the diamond value chain?

• A. The last portion of the diamond value chain and is mostly the retailer-consumer end.
• B. The initial mining operations.
• C. Middle processes like cutting and polishing.
• D. The wholesale distribution.

Answer: (A)

Downstream is the final phase of the diamond value chain, focused on delivering the finished product to the end consumer. It covers activities that connect the diamond to buyers: retailing through jewelry stores and online platforms, marketing to customers, sales channels, and after-sales service or warranties. This stage is last because the earlier steps—mining and rough processing (upstream) and cutting, polishing, and distribution (midstream)—create and move the product toward the market, while downstream finishes the journey by selling to and supporting the buyer. The other options point to earlier stages: mining is upstream, cutting and polishing are midstream manufacturing steps, and wholesale distribution is part of midstream logistics rather than the consumer-facing end.
