De Beers Group's blockchain-enabled traceability platform Tracr reached a significant milestone in 2025, with more than 5 million rough diamonds individually scanned and registered, up from 2.8 million cumulative registrations reported in 2024.
The platform also registered over 750,000 polished diamonds, supporting traceability across additional stages of the value chain.
Okavango Diamond Company joined the Tracr ecosystem during the year, registering diamonds from its January 2025 sales onwards.
Tracr continued to work with laboratories, including through the GIA PROV-T initiative, which allows provenance information to be referenced on grading reports.
A core capability of the platform is rough-to-rough matching, which compares producer and manufacturer scans using proprietary algorithms, enabling country-of-origin information to be surfaced for Diamond Trading Company diamonds.
During 2025 and early 2026, Tracr scaled objective rough-to-rough verification, enabling the transmission of a single country of origin to manufacturers, with work underway to introduce rough-to-polished matching more widely as platform capabilities develop.
De Beers' long-term ambition is for Tracr to be adopted industry-wide as a platform that enables participants to record and share traceability information on natural diamonds as they move through the value chain.
Below are key questions and answers drawn from the company's 2025 Sustainability Report.
How did Tracr expand its use across the diamond industry in 2025?
During 2025, Tracr expanded its use across the diamond industry. Over 5 million rough diamonds have been scanned and registered on the platform…up from 2.8 million cumulative registrations reported in 2024. More than 750,000 polished diamonds have also been registered, supporting traceability across additional stages of the value chain.
What is Tracr's rough-to-rough matching capability?
A core capability of the Tracr platform is rough-to-rough matching. This process compares producer and manufacturer scans using proprietary algorithms, enabling country-of-origin information to be surfaced for Diamond Trading Company diamonds.
Which new participant joined the Tracr ecosystem in 2025?
The Tracr ecosystem also grew during the year. Okavango Diamond Company joined the platform in 2025, registering diamonds from its January 2025 sales onwards. Tracr also continued to work with laboratories, including through the GIA PROV-T initiative, which allows provenance information to be referenced on grading reports.
What did Tracr achieve in scaling verification during 2025 and early 2026?
During 2025 and early 2026, Tracr scaled objective rough-to-rough verification, enabling the transmission of a single country of origin to manufacturers. In October 2024, De Beers Group announced that it would provide country-of-origin data for all De Beers-sourced rough diamonds above 1.25 carats newly registered on the Tracr platform. From the start of 2025, this was extended to rough diamonds above 1 carat in size. This aligned with diamond import requirements for G7 countries and expanded access to verifiable provenance data.
How does Tracr support De Beers' Origins strategy and which organisations use it?
Tracr operates in alignment with the Group's Origins strategy. The platform is used by a range of industry participants, including Responsible Jewellery Council-certified laboratories. Collaboration with the Gemological Institute of America and the Institute of Diamonds helps support consistent application of provenance standards and confidence in traceability data.
How does Tracr support G7 country import requirements?
In October 2024, De Beers Group announced that it would provide country-of-origin data for all De Beers-sourced rough diamonds above 1.25 carats newly registered on the Tracr platform. From the start of 2025, this was extended to rough diamonds above 1 carat in size. This aligned with diamond import requirements for G7 countries and expanded access to verifiable provenance data. Supporting this ambition, in 2025 we launched a collaboration with diamond traceability technology company Sarine to develop a digital portal designed to give customs officials access to provenance information for diamonds entering G7 markets. The expansion of the Tracr platform's reach represents the key area of future focus for the work on provenance.
What is De Beers' long-term ambition for Tracr?
Our long-term ambition is for Tracr to be adopted industry-wide as a platform that enables participants to record and share traceability information on natural diamonds as they move through the value chain.
What was GemFair's first retail collaboration, and what improvements were made to the ASM Assurance Programme in 2025?
GemFair progressed towards bringing ASM diamonds to market through its first retail collaboration with De Beers London. The Riverborn capsule collection was unveiled during the Couture week in Paris...The ASM Assurance Programme was upgraded, broadening access and enhancing traceability technology to support faster diamond logging at source.
By how much did diamond purchases under GemFair increase in 2025, and how many miners were extended access to finance?
Membership growth supported increased purchasing volumes, with the number of diamonds purchased rising by 54% in 2025. Access to finance was extended to 55 miners in 2025, supporting operating costs, strengthening commercial relationships and improving standards and wage payments.
