The World Diamond Council (WDC) has fully transitioned to an expanded System of Warranties, broadening its scope beyond conflict diamonds to encompass human rights, labor standards, anti-corruption, and anti-money laundering controls across the global diamond supply chain.

First introduced in 2002 to complement the Kimberley Process for rough diamonds, the voluntary self-regulatory system applies to transactions involving polished diamonds and finished jewelry.

Following a five-year transition period that concluded on Sept. 21, companies trading in diamonds are now required to register on a dedicated WDC digital platform and complete an annual online self-assessment to maintain compliance.

Upon completing the evaluation, businesses receive a unique identification number to include alongside updated warranty declarations on commercial invoices and memos. The WDC initiated the revision in 2017 to modernize industry self-regulation and ensure broader ethical sourcing standards across intermediate and retail markets.
