Beyond cutting and polishing, what additional value-added activity occurs in the diamond supply chain?

• A. Jewelry assembly and setting
• B. Mining exploration
• C. Insurance analysis
• D. Retail marketing

Answer: (A)

Adding value happens when a loose diamond is transformed into a finished piece of jewelry through assembly and setting. After the gem is cut and polished, it’s paired with metal and crafted into rings, necklaces, bracelets, or earrings, with the stone securely mounted using settings like prongs or bezels. This process adds craftsmanship, design, branding, and presentation, which collectively raise the product’s value far beyond the gemstone alone. Other options fit earlier or supporting roles in the chain—mining exploration is an upstream activity to discover new stones, insurance analysis is risk management, and retail marketing focuses on selling rather than increasing the physical value of the item.
