TL;DRDe Beers is using blockchain to defend natural diamonds against lab-grown rivals. GIA’s acquisition of a 30% stake in Tracr gives the provenance platform industry-wide credibility, but with diamond prices down sharply and lab-grown stones grabbing market share, technology alone may not justify the premium.
The natural diamond industry has a problem it cannot see with the naked eye. Lab-grown stones are now virtually identical to mined gems, they cost a fraction of the price, and the broader tech landscape of 2025 has only accelerated their rise.
De Beers Group, the world’s largest diamond producer and distributor, is betting that blockchain can provide what geology alone no longer does: proof that a stone is worth its price tag.
GIA buys into Tracr
The Gemological Institute of America (GIA) has agreed to acquire a 30% stake in Tracr, the De Beers-backed firm behind a blockchain platform that traces diamond origins. The deal, announced in June 2026, marks a significant step towards making Tracr an independent, industry-wide infrastructure.
