Feriel Zerouki Departs De Beers: A Legacy of Ethical Leadership in the Diamond Industry
De Beers Group has announced the departure of Feriel Zerouki, its esteemed Chief Trade and Industry Officer and a pivotal member of the Executive Committee. This significant announcement marks the conclusion of a remarkable and transformative 20-year tenure with the world-renowned diamond company. Zerouki is set to step down at the end of October 2025, leaving behind an indelible legacy characterized by unwavering integrity, groundbreaking innovation, and unparalleled global leadership in the crucial area of responsible diamond sourcing. Her contributions have not only shaped De Beers’ internal policies but have also set new benchmarks for ethical practices across the entire diamond supply chain, cementing her reputation as a visionary leader dedicated to transparency and accountability.
A Two-Decade Journey of Transformation and Ethical Innovation
Feriel Zerouki joined De Beers in 2005, embarking on a career that would see her rise to become one of the company’s most influential and respected voices. Over two decades, she dedicated herself to shaping the future of ethical trade within the diamond industry, consistently pushing for higher standards and greater transparency. Her strategic vision and passionate advocacy were instrumental in driving forward initiatives that have had a profound and lasting impact on how diamonds are sourced, traced, and perceived globally. Zerouki’s journey at De Beers reflects a deep commitment to not just commercial success, but to ensuring that every diamond brings positive impact at every stage of its journey from mine to market.
Pioneering Transparency: The Impact of Tracr and GemFair
Among her most notable achievements, Zerouki played a pivotal role in the creation and implementation of two transformative initiatives: Tracr and GemFair. Tracr, De Beers’ pioneering blockchain-based traceability platform, revolutionized the way diamonds are tracked. This innovative system provides an immutable record of a diamond’s journey, from its rough state at the mine to its polished form, ensuring authenticity and provenance. By leveraging blockchain technology, Tracr has significantly bolstered consumer confidence, offering an unprecedented level of transparency that was once thought impossible in such a complex global supply chain.
Complementing Tracr’s large-scale traceability, Zerouki also spearheaded GemFair, an initiative specifically designed to empower artisanal and small-scale miners (ASM). GemFair focuses on bringing transparency and responsible practices to a sector that often faces significant challenges. Through this program, De Beers provides technology, training, and a secure route to market for ethically sourced artisanal diamonds, ensuring fair prices and improved working conditions for miners. This initiative addresses critical social and environmental issues, demonstrating a holistic approach to responsible sourcing that extends beyond industrial mining operations. Together, Tracr and GemFair have not only strengthened transparency and accountability throughout the diamond supply chain but have also set a new standard for ethical engagement across all segments of the industry, truly redefining what it means to source diamonds responsibly.
Global Leadership: Championing Ethics on the International Stage
Beyond her remarkable corporate achievements at De Beers, Zerouki has also been a formidable driving force on the global stage. As President of the World Diamond Council (WDC), a position she will hold until May 2026, she has continued to champion critical reforms within the Kimberley Process (KP). The Kimberley Process Certification Scheme is an international multi-stakeholder initiative established to prevent the flow of conflict diamonds, and Zerouki’s leadership has been crucial in advocating for its modernization and greater effectiveness. Her work at the WDC extends to promoting robust and credible mining-origin certification systems, ensuring that consumers can trust the provenance of their diamonds and that the industry adheres to the highest ethical standards. Her tenure at the WDC has been marked by a relentless pursuit of industry-wide improvement, fostering collaboration among governments, industry, and civil society to uphold the integrity of the diamond trade worldwide.
