De Beers pushes blockchain diamond tracing via Tracr as lab-grown gems disrupt market
Summary
De Beers is advancing its blockchain platform Tracr, which traces diamond origins, as the GIA agreed to acquire a 30% stake in the platform in June 2026. Tracr has registered over five million rough diamonds at source, covering about two-thirds of De Beers' rough diamond production by value, and is positioned to become independent industry infrastructure. Meanwhile, the diamond market faces significant pressure from lab-grown stones that are virtually identical to mined gems but cost a fraction, contributing to a sustained decline in the IDEX Diamond Price Index since its 2022 peak.
