Chain of custody documentation for diamonds tracks the movement of diamonds from mine to consumer, enabling provenance claims and supporting compliance with Kimberley Process and RJC requirements. A robust chain of custody is increasingly required by consumers and retailers seeking assurance of diamond origin.
Mine-to-Market Traceability
Mine-to-market traceability requires documentation at each stage of the diamond supply chain: mining (mine production records, government export permits); rough diamond trading (KPCS certificates, trading records); cutting and polishing (intake and output records, weight and quality data); jewellery manufacturing (diamond intake records, finished product records); and retail (provenance documentation for consumers).
