Since the start of the Kimberley Process, members of the diamond trade have been adding a declaration to their sales documents, each time a transaction is finalized along the entire supply chain, from mine to retail. It’s become a customary act in our industry, but a massively important one, for it verifies to the next participant in the supply chain that the diamonds involved are compliant with the Kimberley Process Certification Scheme (KPCS), and thus can be considered “conflict free” according to KP doctrine.
