What is a key reason for expanding traceability in the diamond supply chain?

• A. To ensure ethical sourcing and regulatory compliance.
• B. To increase price without justification.
• C. To limit consumer choices.
• D. To simplify laboratory testing.

Answer: (D)

Expanding traceability in the diamond supply chain is about proving origin and ensuring responsible sourcing to meet ethical standards and regulatory requirements. By tracking each diamond’s journey from mine to market, stakeholders can verify that it is conflict-free and compliant with laws and standards like the Kimberley Process. This transparency builds trust with retailers, regulators, and consumers, helps prevent illicit material from entering the market, and makes due diligence more straightforward for companies. Technologies such as unique serialisation and secure ledgers support a verifiable chain of custody at every handoff.

While provenance data can aid laboratory work by providing context, the main aim of traceability is origin verification and compliance, not simply reducing the complexity of lab testing.
