De Beers Group Chief Trade and Industry Officer Feriel Zerouki is stepping down at the end of October 2025. She joined De Beers in 2005 and has played a central role in shaping its initiatives in ethics, provenance and industry integrity. 

A member of De Beers’ Executive Committee, Zerouki spearheaded the launch of Tracr and GemFair, two major initiatives that advanced traceability and responsible sourcing in the diamond industry.

She also led efforts to enhance the Kimberley Process and improve transparency in mining-origin certification as president of the World Diamond Council, a role she holds until the end of May 2026.

“Feriel has played a pivotal role in establishing and upholding the highest standards of integrity and provenance within De Beers and across the global diamond industry,” De Beers Group CEO Al Cook said. “Her strategic insight and leadership have contributed meaningfully to initiatives that will leave a lasting impact on the sector.” 

Zerouki said: “Being part of De Beers has been an extraordinary journey. I am immensely proud of what we have built together and deeply grateful for the people and partnerships that have defined these 20 years. I leave with pride in our shared achievements and with excitement for what lies ahead.”
