Jillian Wolk has been appointed CEO of diamond miner De Beers' diamond traceability subsidiary Tracr, with effect from May 1. She succeeds Wesley Tucker, who stepped down at the end of February after having led the Tracr business through its formative and scaling phases.

She has held senior leadership roles across the jewellery, luxury and technology sectors. Most recently, she served as Growth & Strategic Initiatives VP at the Gemological Institute of America (GIA), where she developed new services and drove diversified revenue, strengthened commercial strategy and supported significant industry-wide grading initiatives. Having worked closely with the Tracr team in her role at GIA, Jillian brings a deep understanding of Tracr and its mission.

Prior to the GIA, Wolk held senior executive roles in the jewellery and technology industries, including business operations VP at Swarovski US, where she oversaw multiple business lines and led major operational and brand initiatives across the Americas. Her background spans commercial leadership, legal and governance expertise and technology‑enabled innovation, positioning her well to lead Tracr as it continues to develop trusted, scalable traceability solutions for the diamond industry.

“Jillian brings a strong combination of industry knowledge, commercial leadership and strategic insight. Her insights across jewellery, technology and governance, together with her background working with Tracr, provide her with a wealth of valuable experience to lead the business into its next phase,” says De Beers diamond trading executive VP Paul Rowley.

“I am honoured to be joining Tracr and help shape its future as a vital storytelling tool for the diamond industry. With its leading technology platform and industry network, Tracr has an increasingly significant role to play in supporting trust, transparency and confidence across the diamond industry. I look forward to working with the team and industry partners as the platform continues to develop and scale,” comments Wolk.

She will be based in New York and will work closely with Tracr’s global team and stakeholder network.
