The Evolution of Diamond Tracking Technology
The diamond industry has undergone a remarkable transformation in how it tracks these precious gems from mine to market. What began as a paper-based system reliant on certificates and manual verification has evolved into a sophisticated digital ecosystem powered by blockchain technology.
From Paper Certificates to Digital Ledgers
Traditional diamond tracking relied heavily on paper documentation that accompanied stones through the supply chain. These certificates, while better than no tracking at all, were vulnerable to forgery, loss, and human error. The process was inefficient, opaque, and failed to provide consumers with verifiable assurance about a diamond's origins.
In the early 2010s, the industry began implementing digital solutions to address these shortcomings. However, these early systems still depended on centralized databases controlled by individual companies or organizations. The breakthrough came with the adoption of blockchain technology, which introduced a distributed approach to record-keeping that fundamentally changed what was possible in diamond tracking.
Why Blockchain Matters for Diamond Provenance
Blockchain technology has revolutionized diamond tracking through several key innovations. First, it creates an immutable record that cannot be altered retroactively without consensus from the network participants. Once information about a diamond is recorded on the blockchain, it becomes a permanent part of the digital ledger.
The decentralized nature of blockchain means verification doesn't rely on a single authority. Instead, multiple participants in the network validate transactions, creating a consensus-based system that dramatically reduces the potential for fraud or manipulation.
Real-time tracking across the entire supply chain becomes possible as each transaction is recorded chronologically and transparently. This visibility allows all authorized participants to see the complete journey of a diamond from extraction to retail.
Finally, blockchain employs sophisticated cryptographic security protocols that protect the integrity of the data while allowing appropriate access to different stakeholders. This combination of security and transparency addresses many of the shortcomings of previous tracking systems.
How Does De Beers' Tracr Blockchain Platform Work?
De Beers tracks diamonds using blockchain technology through its Tracr platform. This innovative system represents one of the most ambitious applications of distributed ledger technology in the mining industry evolution and gemstone sectors.
The Technical Foundation of Tracr
Tracr utilizes distributed ledger technology to create permanent, immutable records of each diamond registered in the system. The platform is designed specifically for the diamond industry, taking into account the unique characteristics and supply chain considerations of diamond production and distribution.
Each diamond registered on Tracr receives a unique digital identifier that serves as its digital passport throughout the supply chain. This identifier is linked to the diamond's physical characteristics, creating a digital twin that travels alongside the physical stone.
The platform has been designed with integration capabilities that allow it to work with existing industry systems, making adoption more seamless for participants across the supply chain. This interoperability has been crucial to the platform's expanding adoption.
Access to Tracr is permission-based, with different stakeholders having appropriate levels of access depending on their role in the supply chain. This ensures that sensitive commercial information remains protected while still enabling transparency where it matters most.
The Registration and Verification Process
The journey of a diamond on Tracr begins at the source. When a diamond is extracted, it receives a unique digital identifier that will follow it through its entire lifecycle. This process involves recording the diamond's country of origin and the specific mine where it was recovered.
Physical characteristics are documented using specialized imaging technology that captures the diamond's unique features. These characteristics serve as a digital fingerprint that can be used to verify the diamond's identity at subsequent points in the supply chain.
This data is encrypted and stored across multiple nodes in the blockchain network, ensuring that no single party controls the information. The distributed nature of the storage adds a layer of security and prevents unauthorized alterations.
As the diamond moves through the supply chain—from mine to cutting facility to wholesaler to retailer—verification occurs at each transfer point. This creates an unbroken chain of custody that can be audited and verified at any time.
What Are the Key Achievements of De Beers' Blockchain Initiative?
Since its implementation, De Beers' blockchain tracking system has achieved significant milestones that demonstrate the transformative potential of this technology in the diamond industry.
Impressive Tracking Milestones
Nearly 3 million diamonds have been registered on the Tracr platform since 2022, representing a substantial portion of De Beers' production. This scale of implementation demonstrates that blockchain tracking is viable at commercial volumes in the diamond industry.
The system now provides complete verification capability from rough-to-rough and rough-to-polished stages, creating unprecedented transparency throughout the diamond journey. This end-to-end tracking closes gaps that existed in previous systems where visibility was often lost during certain stages of processing.
One of the most significant achievements is the availability of full country-of-origin data for all De Beers-sourced rough diamonds over one carat registered on the platform. This addresses a critical concern for consumers who want assurance about where their diamonds come from.
The platform's adoption has expanded beyond De Beers' own operations to include other producers such as ODC (Okavango Diamond Company) and Mountain Province. This broader participation strengthens the overall system by incorporating more of the global diamond supply into the tracked ecosystem.
The ORIGIN Program Launch
In 2024, De Beers launched its ORIGIN program, a breakthrough initiative that extends blockchain tracking all the way to the retail environment. This polished diamond program allows retailers to access stones tracked through the Tracr platform, providing a direct link between blockchain technology and consumer experience.
Through ORIGIN, retailers can offer consumers comprehensive information about each diamond's journey from mine to market. This includes details about the extraction process, cutting and polishing, and the various hands through which the diamond passed.
A unique aspect of the ORIGIN program is the inclusion of social impact details that highlight the positive community contributions associated with diamond production. This connects consumers not just to the physical journey of their diamond but to the human stories and positive development outcomes behind it.
As Sandrine Conseiller, CEO of Brands & Diamond Desirability at De Beers Group, noted: "When someone chooses a De Beers natural diamond, they're not only celebrating a personal milestone – they are helping shape a brighter future for the people and places behind it."
