What does traceability mean in the diamond supply chain?

• A. The ability to verify the history of a stone through the supply chain.
• B. A strategy for marketing diamonds.
• C. A method to grade color of diamonds.
• D. A way to compute price per carat.

Answer: (A)

Traceability means being able to verify the complete history and journey of a diamond as it moves from the mine to the final consumer. It involves documenting each step—origin, processing, sorting, distribution, and sale—so that every link in the supply chain can be traced and trusted. This supports ethical sourcing, helps prevent conflict diamonds, and allows buyers and professionals to confirm provenance through records, certifications, and chain-of-custody tracking. The other options address marketing, color grading, or price calculations, which are different aspects of the diamond trade and do not capture the idea of following a stone’s history through the chain.
