How does blockchain help with ethical diamond sourcing?

By recording every step of a diamond's journey from mine to market on an immutable ledger, blockchain makes it much harder to introduce conflict diamonds into a legitimate supply chain. Each stone can be traced back to its verified origin.

Is blockchain used by jewellery brands today?

Yes, a growing number of brands and miners use blockchain-based systems. De Beers launched the Tracr platform, and other industry initiatives use similar technology to document provenance for diamonds and coloured stones.

Is a blockchain certificate the same as a GIA certificate?

No. A GIA certificate is a grading report describing a diamond's physical characteristics like cut, colour and clarity. A blockchain record is a provenance document tracing the stone's supply chain history. Some diamonds have both.

What is blockchain in jewellery?

Definition

Blockchain is a decentralised digital ledger that records transactions or data across many computers so that no single entry can be altered without changing all subsequent records, making it very difficult to falsify. In the jewellery and diamond industry it is increasingly used to track provenance, recording where a diamond was mined, how it was cut and certified, and who has owned it since, creating a transparent chain of custody that buyers can verify. Companies like Tracr have applied blockchain to diamonds specifically to support ethical sourcing claims.
