The Story of Your Diamond Backed by Blockchain

We partnered with Everledger, a digital transparency company, to offer diamonds backed by the blockchain technology. Our purpose is to provide diamonds that have a more transparent story and meet higher standards of ethical sourcing.

Blockchain technology allows data to be recorded securely and unalterably as an asset, such as a diamond, an artwork, or a bottle of fine wine. By converging this record with other technologies, Everledger creates a unique digital identity for the asset and makes it available to all stakeholders. The resulting lift in transparency, confidence and trust lays the foundation for whole industries to advance.

Thanks to Everledger we can know exactly where a diamond came from and what it went through as it journeyed from the mine to the retailer and then to the customer. Everledger’s unique blockchain diamond tracking technology pinpoints where the diamond was mined and traces its steps as it went through the cutting and polishing process. Everledger also records every time the diamond changes hands and crosses borders as it travels to the retailer. 

Backing a diamond on the blockchain gives the following benefits:

  • A clearer proof of provenance.
  • An additional guarantee of ethicality.
  • A traceable history from the ground to you.
  • Greater transparency in its documentation.
  • Validated claims of social and environmental sustainability.
  • Evidence of environmental performance and use of renewable energy in the mining and polishing of diamonds.

Just to be clear, all of our diamonds are conflict-free and ethical. They have been certified by the Kimberley process and come from ethical mines that invest in the well-being of their miners and the environment. But our blockchain-enabled diamonds are extra special.

Each blockchain-enabled diamond has its own unique story and paves the way for diamond sourcing to become even more transparent and responsible.

How does Everledger use blockchain to trace a diamond’s story?

Everledger uses the blockchain and a symphony of other technologies to capture a diamond’s story and eliminate doubts about its provenance and journey.

A diamond’s journey from the mine to a retailer is complex and the gem changes hands multiple times. During these exchanges, a diamond’s individual information can be lost, incorrectly copied and sometimes even corrupted. 

Everledger’s technology helps prevent this from happening by recording and checking all of the diamond’s paperwork. These checks may include the mine invoice, the Kimberley Process Certificate (KPC) details, bills of entry, airway bills, supplier invoices, and grading certificates, just to name a few. 

Everledger uses artificial intelligence (AI) technologies, such as optical character recognition (OCR), to triangulate all of the documents provided and verify these checks against claims made. Only after all of these checks have been successfully completed is the information  uploaded to the database and then automatically written on the blockchain. 

This marks the beginning of the diamond’s journey on the blockchain. Suppliers can then upload pictures of the diamond and  record its  identifying characteristics to form the first block on the diamond’s blockchain. Most importantly, once the data has been verified and uploaded, it is impossible to alter the record. This makes the supply chain more transparent than ever before.


Everledger blockchain-enabled diamonds prove 6 vital claims:

1. Legality

Every person and business related to the diamond are legitimate and act in good faith.

2. Origin

Clear proof of origin.

3. Human rights

Guarantees that the people and businesses that worked with the diamond do not use child or slave labour in their internal processes.

4. Chain of custody

A timeline proving who had possession of the diamond from the time it was mined until it reached the retailer.

5. Circularity

Contribution to a circular economy where waste and pollution are minimized, recycling and reuse are encouraged, and natural systems are renewed.

6. Environmental Performance

A record of how participating businesses invest in protecting the environment by sharing energy consumption, waste production, and transportation data.


Blockchain technology captures the unique identity of a diamond in two ways:

1. The diamond has a digital identity.

2. The owner receives digital ownership.

Are lab-grown diamonds more eco-friendly than natural diamonds?

We have noticed recently that multiple claims are circulating about how lab-grown diamonds are more eco-friendly than natural diamonds.

These claims must be taken with caution because growing diamonds in a lab consumes large amounts of energy. If that energy comes from renewable sources, the diamonds may qualify as eco-friendly. Unfortunately, most diamond labs burn fossil fuels to produce energy and this can harm the environment more than an ethical diamond mine.

Everledger’s blockchain technology can also be beneficial for laboratory-grown diamonds because it allows laboratories to register their energy usage and sources, as well as a variety of other factors that impact the environment. 

If you decide to purchase a blockchain-enabled diamond from a lab, you can be confident that it is eco-friendly. 

How much energy does the Everledger blockchain platform use?

Blockchain networks, like cryptocurrencies, require large amounts of energy to secure and verify digital records. Some cryptocurrencies consume an average of 275 kilowatt-hours of energy per transaction. This leaves a sizeable carbon footprint on the environment.

Everledger has taken steps to make its blockchain network more energy-efficient. The network is built on the Hyperledger Fabric Raft consensus protocol which uses approximately 10 billion times less energy per transaction than cryptocurrencies. 

Through their technology and also their commitment to the environment, Everledger makes it possible for us to offer you diamonds that are guaranteed to be eco-friendly at the highest level.

Why do we provide blockchain-enabled diamonds only on request?

Blockchain-enabled diamonds are still a new technology and only a limited number of diamonds on the market have been blockchain verified. We expect to see this number grow with time but for now, we have opted to only provide them on request.
