The World Diamond Council (WDC) and the Responsible Jewellery Council (RJC) have agreed to work together on key issues such as the Kimberley Process (KP), conflict diamonds and sustainability.The two organizations have entered into a cross-membership partnership, meaning the RJC has become a member of the WDC, and the WDC has become a member of the RJC, they said Tuesday. The groups have also signed mutual codes of conduct.An RJC official will join the WDC's Kimberley Process (KP) Task Force and participate in discussions about matters including the expansion of the KP's definition of conflict diamonds, principles for responsible diamond sourcing, and the worldwide adoption of the WDC's System of Warranties. Meanwhile, a WDC official will become part of an RJC task force that focuses on ensuring the jewelry and watch industry achieves the United Nations' Sustainable Development Goals (SDGs).

"Through this partnership, we can do more to increase understanding of the [Kimberley Process Certification Scheme] and present a united industry front dedicated to broadening its scope through the expansion of the definition of conflict diamonds."Image: Rough diamonds.
