London—Tracr, the blockchain platform De Beers Group developed to track diamonds through the supply chain, soon will have a new leader.
The diamond miner and marketer announced Monday that Jillian Wolk has been appointed Tracr CEO, effective May 1.
She succeeds Wesley Tucker, who stepped down at the end of February after five years with De Beers scaling Tracr. Development of Tracr began in 2018 and the wide rollout of the platform took place in 2022.
Wolk will be based in New York.
She joins Tracr from the Gemological Institute of America, where she has spent the past four years working as the vice president of growth and strategic initiatives.
In this role, she worked to develop new services, drive diversified revenue, strengthen the lab’s commercial strategy, and support significant industry-wide grading initiatives.
At GIA, Wolk worked closely with the Tracr team and has a “deep understanding” of the blockchain platform and its mission, De Beers said.
