The World Diamond Council (WDC) was established to represent all sectors of the diamond industry, from mine to market, in the Kimberley Process (KP). According to the WDC website “it was the industry that provided the blueprint for the certification system.”
As the KP only regulates the trade in rough diamonds, the WDC introduced a System of Warranties (SOW) that purports to extend the remit of the KP to cut and polished diamonds. It does this by the simple inclusion of a statement on invoices indicating that the seller believes the diamonds are conflict-free.
Although this does not change the KP in any way, jewellers use the SOW to claim KP-compliant diamonds “conflict-free” even though a significant percentage of these diamonds fund regimes guilty of serious human rights violations.
