Diamond Traceability Technology

Diamond traceability technology has advanced significantly in recent years, driven by consumer demand for ethically sourced diamonds and regulatory requirements for conflict-free certification. Key technologies include blockchain-based provenance platforms, laser inscription, spectroscopy, and digital diamond passports.

Blockchain Diamond Traceability

Tracr (De Beers), Everledger, and other platforms use blockchain to create immutable records of diamond provenance from mine to retail. Each diamond is assigned a unique digital identity based on its physical characteristics (carat, colour, clarity, cut) and tracked through the supply chain. Blockchain records include KP Certificate numbers, rough diamond origin, and processing history.

Laser Inscription

Laser inscription on the diamond girdle provides a permanent, tamper-resistant identifier linking the physical diamond to its grading report and provenance records. GIA, IGI, and other grading laboratories offer laser inscription services. Laser-inscribed diamonds can be verified using magnification equipment.
