TRACR LIMITED (Headquarters: London, UK, CEO: Jillian Wolk), which operates "Tracr," a digital platform for large-scale tracking of natural diamond origins and provenance from mine to market, announces that De Beers Group and GIA (Gemological Institute of America) have entered into a definitive agreement for GIA to acquire a 30% stake in Tracr. This agreement marks a significant milestone in Tracr's evolution into an independent platform. It also demonstrates GIA's strong confidence in Tracr's role as an infrastructure for promoting industry-wide diamond provenance and traceability. GIA's investment builds upon the initiative launched in 2023 to include provenance information for diamonds registered on Tracr in GIA diamond grading reports. This investment is a major step forward in further strengthening Tracr's long-term credibility across the entire diamond value chain.

Comment from Al Cook, CEO of De Beers Group

"Consumers have a right to accurate information about the origin and journey of their diamonds. De Beers has been using Tracr to provide diamond provenance data for several years, and we believe provenance provision should be the industry standard. We are proud that Tracr will evolve into an independent, cross-industry platform with GIA, fulfilling our commitment to open Tracr more broadly to the industry. We look forward to working with GIA to drive transparency throughout the diamond pipeline."

Comment from Pritesh Patel, President and CEO of GIA

"GIA's mission is to protect the integrity of the gem and jewelry industry, built on a foundation of honesty, fairness, and consumer trust. Through our multi-year collaboration with Tracr, we have become increasingly confident that combining GIA's independent grading and appraisal expertise with blockchain-recorded diamond origins and provenance can bring a new dimension of transparency to the diamond industry. As Tracr continues its global growth, we see a significant opportunity to deliver trusted origin and provenance information from the mine to the consumer. We are proud to deepen our commitment through this investment and shape the next evolution of transparency, traceability, and trust across the industry."

Comment from Jillian Wolk, CEO of Tracr

"The evolution of Tracr into an independent platform, initiated by GIA's investment, builds a strong foundation for the future. As we continue to scale the platform and welcome more producers, we look forward to Tracr enabling every registered diamond to experience its individual journey. Each diamond holds a unique story woven from its origin and the artisan's skill. Together with Tracr, we will bring those stories to consumers worldwide."

Tracr's Current Status and Future Outlook

De Beers has been developing Tracr since 2018, and it has now grown into an industry-leading distributed blockchain platform that records information from the moment a diamond is mined. In 2023, the platform was opened to the entire diamond industry, establishing it as a common foundation for industry-wide proof of natural diamond origin and provenance throughout the entire process from rough stone to polished gem. Currently, over 5 million rough diamonds have been registered for provenance on Tracr, representing approximately two-thirds of De Beers' rough diamond production by value. All diamonds mined from De Beers' mines have their country of origin registered on Tracr, and since January 2025, more detailed rough diamond data has also been recorded.
