GIA has taken a significant step into the diamond traceability space by acquiring a 30% stake in Tracr, the blockchain-based provenance platform originally developed by De Beers. The move marks an important milestone in Tracr’s evolution from a company-backed initiative to a broader industry-focused solution.
The investment builds upon a partnership that began in 2023, when provenance information sourced through Tracr started appearing on eligible GIA grading reports. By deepening its involvement, GIA aims to help accelerate the adoption of verified origin data and strengthen confidence in diamond traceability throughout the supply chain.
According to De Beers Group CEO Al Cook, consumer expectations around transparency continue to rise, making provenance an increasingly important aspect of the diamond buying journey. He noted that opening Tracr to wider ownership has been a long-term objective and that GIA’s participation represents a meaningful step towards establishing provenance as a shared industry standard.
GIA President and CEO Pritesh Patel said the organisation sees significant value in combining its expertise in diamond grading and identification with blockchain-enabled provenance technology. He highlighted the opportunity to deliver reliable, verifiable information that follows a diamond’s journey from its source through to the end consumer.
Tracr CEO Jillian Wolk described the investment as a catalyst for the platform’s next stage of growth. She added that broader participation from producers and industry stakeholders would further strengthen the platform’s ability to document and communicate the unique journey of individual diamonds.
First launched in 2018, Tracr was opened to the wider diamond trade in 2023 as a scalable system designed to track natural diamonds from rough production through to polished stones. The platform has since registered more than five million rough diamonds at source and continues to expand its provenance capabilities. Since early 2025, it has also supported single-country-of-origin information for eligible De Beers diamonds, enhancing the level of transparency available to the market.
The latest development reflects a growing industry emphasis on traceability, with provenance increasingly becoming a key component of consumer trust and diamond differentiation.
