World Diamond Council Reminds Industry of Approaching System of Warranties Deadline

 

The World Diamond Council (WDC) has issued a reminder to the global diamond industry that the transition period for its revised System of Warranties (SoW) will officially end on 21 September 2026.

With fewer than three months remaining, all businesses involved in the trade of rough diamonds, polished diamonds and diamond jewellery are urged to ensure they have adopted the updated declaration. From 21 September, the revised declaration will become the only recognised System of Warranties statement for all diamond transactions.

The System of Warranties is a self regulated industry initiative developed by the World Diamond Council to strengthen and extend the Kimberley Process Certification Scheme (KPCS). The framework requires companies to include a warranty declaration on invoices and transaction documents whenever diamonds change ownership, whether they are rough, polished or mounted in jewellery.

The declaration provides assurance that the diamonds originate from legitimate sources and have been traded in accordance with recognised industry standards. By passing this declaration through every stage of the supply chain, the System of Warranties reinforces transparency, responsible sourcing and consumer confidence across the global diamond industry.

World Diamond Council Executive Director Elodie Daguzan emphasised the continuing importance of the initiative.

“The System of Warranties remains a cornerstone of trust in the global diamond supply chain, linking companies through a shared commitment to responsible sourcing,” she said.

She added that the 2021 revision reflects the evolving expectations placed on the diamond industry by incorporating broader due diligence requirements, including commitments to human rights, anti corruption measures and anti money laundering practices.

The World Diamond Council is encouraging all companies involved in diamond trading to review their invoice templates and business documentation well before the September deadline to ensure full compliance with the revised System of Warranties.

For laboratories, manufacturers, wholesalers, retailers and other participants in the diamond supply chain, the updated declaration represents another important step towards maintaining the integrity, transparency and ethical standards expected throughout the global diamond industry.
