The WDC System of Warranties extends beyond the Kimberley Process Certification Scheme (KPCS) to cover the entire supply chain, from mine to market. It’s a voluntary system whch requires that every time diamonds are bought or sold, a warranty statement is included on the invoice or memo, declaring that the diamonds have been purchased from legitimate sources, not involved in funding conflict and which are in compliance with United Nations resolutions.

While the KPCS is crucial in preventing conflict diamonds from entering the market, the SoW plays an equally important role in fostering transparency and accountability throughout the diamond pipeline. It assures customers and stakeholders that the diamonds they are purchasing have been sourced ethically and responsibly.

The SoW represents a significant enhancement to our commitment to responsible diamond trading. Its updated framework extends the scope of the original warranty, ensuring not only that diamonds are conflict-free but also that they adhere to broader universal standards, including human rights, fair labor practices, and anti-corruption and anti-terrorism financing.

Under the recently revised SoW system, all companies in the diamond supply chain are encouraged to conduct a thorough self-assessment to verify their compliance with these expanded requirements. This self-assessment is a crucial step in maintaining transparency and accountability, demonstrating our collective dedication to upholding the highest standards of integrity throughout our entire diamond industry. Successfully completing the self assessment enables companies to issue the revised Warranty Statement on their invoices, word for word.
