Extensive Background in Operations and Innovation

Prior to her role at GIA, Wolk held significant executive positions within the jewelry and technology industries. She previously served as Vice President of Business Operations at Swarovski U.S., where she oversaw multiple business lines and led key operational and brand initiatives across the Americas. Her expertise spans commercial leadership, legal and governance matters, and technology-enabled innovation, positioning her to guide Tracr effectively as it continues to develop trusted and scalable traceability solutions.

Tracr's Vision for Transparency and Trust

Wolk expressed her honor in joining Tracr, viewing the platform as a “vital storytelling tool for the diamond industry.” She emphasized Tracr’s growing importance in fostering trust, transparency, and confidence throughout the diamond pipeline. “I look forward to working with the team and industry partners as the platform continues to develop and scale,” Wolk commented.

Based in New York, Wolk will work closely with Tracr’s global team and its network of stakeholders. The development of Tracr began in 2018, with a wide rollout of the platform occurring in 2022. De Beers Group, a leading diamond company established in 1888, is committed to innovation and sustainability, with Tracr representing a key component of its strategy to enhance the diamond value chain through technology.
