1. Introduction: The Problem with the Diamond Supply Chain |
The diamond industry has long been plagued by issues related to fraud, unethical sourcing, and a lack of transparency. For decades, the term 'conflict diamonds' (also known as 'blood diamonds') has highlighted the role that diamonds play in financing wars, human rights abuses, and the exploitation of workers. The journey of a diamond from the ground to the consumer has often been shrouded in mystery, leading to consumer distrust and the proliferation of illicit trade. The issue of diamond fraud and the absence of transparency within the supply chain have raised serious concerns for both consumers and industry stakeholders alike. |
To combat these problems, the diamond industry has seen the rise of innovative solutions, most notably through blockchain technology. Blockchain offers a transparent, immutable, and decentralized way to track assets as they move through complex supply chains. Combined with AI-powered barcode scanning and digital tracking systems, blockchain presents a promising solution to address these longstanding issues. |
This case study will delve into how De Beers, one of the world's largest and most well-known diamond producers, in collaboration with Everledger, a blockchain technology company, has pioneered a blockchain-based provenance tracking system for diamonds. The goal is to ensure that diamonds are ethically sourced, traceable, and verified as conflict-free. |

3. Tracking the Diamond's Journey: From Mine to Market |
The Everledger blockchain platform provides a digital ledger of a diamond's journey across multiple stages of the supply chain. The process starts with the extraction of the diamond, but every subsequent transaction-sorting, cutting, polishing, and distribution-is also recorded on the blockchain. Each diamond is given a unique digital ID, which is used to track its movement and history. This digital record is linked to the diamond via a QR code or an RFID tag, which are physically attached to the stone or its packaging. |
3.1 Stage 1: Mining |
The process begins when a diamond is mined, either in a controlled environment or through artisanal mining efforts. At this stage, the diamond is given a unique ID that is recorded on the Everledger blockchain. This information includes details such as the mine where the diamond was extracted, the mine's geographical location, and the environmental and ethical practices followed during extraction. |
3.2 Stage 2: Sorting and Grading |
Once the diamond is mined, it undergoes sorting and grading to classify its size, shape, color, clarity, and other characteristics. This information is also entered into the blockchain, creating a detailed record of the stone's attributes. The process of grading is conducted by experienced gemologists, ensuring that the diamond is correctly categorized and that its authenticity is verified. |
3.3 Stage 3: Cutting and Polishing |
After sorting, the diamond is sent to a cutting and polishing facility. Here, it is transformed into its final shape. The cutting and polishing stages are recorded in the blockchain, creating an ongoing audit trail for the diamond. This ensures that every piece of the diamond's journey is traceable, which is crucial in maintaining its provenance. |
3.4 Stage 4: Distribution and Retail |
After the diamond has been cut and polished, it enters the distribution phase, where it is sold to dealers, wholesalers, or directly to retailers. The digital ID on the diamond (via the RFID tag or QR code) is used to track the movement of the diamond through the distribution network. Retailers, consumers, and other stakeholders can access information about the diamond's history at any point in time. |
|
4. The Role of Blockchain in Transparency |
At the heart of the system is the Everledger blockchain, which ensures that the data collected at each stage of the diamond's journey is secure, transparent, and immutable. Blockchain is a decentralized, distributed ledger technology that allows data to be stored across a network of computers. Once data is entered into the blockchain, it cannot be altered or deleted, which guarantees that the provenance information is accurate and trustworthy. |
4.1 Ensuring Authenticity and Preventing Fraud |
One of the most significant challenges in the diamond industry is the prevalence of fraud. This can include everything from counterfeit diamonds to diamonds that have been illicitly mined in conflict zones. By recording every transaction and every touchpoint in the supply chain on the blockchain, De Beers and Everledger have created an effective system for verifying the authenticity of each diamond. If a diamond's provenance information is tampered with or falsified, the discrepancy will be immediately evident on the blockchain, providing a clear warning to stakeholders. |
4.2 Combatting Conflict Diamonds |
Perhaps the most pressing ethical issue addressed by blockchain technology is the problem of conflict diamonds. These diamonds are mined in war zones, often under exploitative conditions, and are sold to fund violent conflicts. The blockchain provides a transparent and secure way to verify that a diamond has not entered the market through illegal or unethical means. By ensuring that each diamond's provenance is traceable from mine to market, blockchain helps prevent conflict diamonds from being sold to consumers. |
4.3 Providing Consumer Confidence |
For consumers, transparency is a critical factor when purchasing luxury items like diamonds. Many consumers today are increasingly concerned about the ethical sourcing of the products they buy, and they want to know whether their diamond was mined and traded under ethical conditions. Blockchain's ability to provide clear, unalterable records of a diamond's journey helps build consumer confidence by assuring them that the diamond they purchase is ethically sourced and free from association with conflict zones. |
|
5. Technology Behind the Solution |

As previously discussed, blockchain technology is the core of Everledger's solution. It provides a secure, transparent, and decentralized ledger for tracking the provenance of diamonds. Each transaction and event in the diamond's journey is recorded on the blockchain, ensuring that no information can be altered or deleted. This guarantees the integrity of the diamond's provenance and helps eliminate fraud. |
5.2 QR Codes and RFID Tags |
Each diamond is tagged with a unique QR code or RFID tag, which is scanned at each touchpoint in the supply chain. QR codes are scannable using smartphones or other devices, while RFID tags use radio waves to transmit information. These tags allow stakeholders to quickly and easily access a diamond's history by scanning the tag at any point in its journey. For consumers, this means they can verify the ethical sourcing of their diamond by scanning the QR code on the diamond's packaging or at the point of sale. |
5.3 AI-Powered Scanners |
To further enhance the tracking process, AI-powered barcode scanners are used to scan QR codes and RFID tags throughout the supply chain. These advanced scanners can quickly read the information contained in the codes and provide real-time data to stakeholders. AI is also used to process and analyze the data generated by the scans, identifying any inconsistencies or potential issues with the diamond's provenance. This enables faster, more accurate tracking of diamonds as they move through the supply chain. |
|
6. Consumer Interaction and Transparency |
Once a diamond reaches the consumer, the journey does not end. Through the use of QR codes and RFID tags, consumers can take an active role in verifying the provenance of their diamonds. By scanning the QR code or RFID tag on the diamond's packaging, consumers can access detailed information about the diamond's journey, including: |
The mine where it was sourced |
The ethical practices employed during its extraction |
The cutting and polishing process |
The distribution chain |
This transparency helps build trust with consumers, who can now be confident that their purchase is both authentic and ethically sourced. Additionally, as more consumers demand transparency in the products they buy, the blockchain-powered tracking system provides De Beers with a competitive edge in a market increasingly driven by ethical concerns. |
