Diamond and Gemstone Provenance for Authentication and Traceability
Microtrace provides a complete provenance solution for diamonds and gemstones using layered security technologies to authenticate each step from mine to market. Combined with blockchain or certification systems, the approach creates a traceable, tamper-resistant link between the physical stone, its identifiers, and the provenance information associated with it.
Complete Chain of Custody
From rough stone to retail certificate, each step is authenticated with proprietary Microtrace technology:
Rough Stone: Molecular Taggant
Rough diamonds are marked with trace levels of a unique Molecular Taggant. This chemical tracer provides covert, high-throughput identification and can be verified using handheld detectors, laboratory equipment, or automated vision systems.
Polished Stone: Laser Barcode Marking
After cutting and polishing, diamonds are laser marked with a proprietary micro-barcode using PhotoScribe systems. These secure 2D barcodes are nearly impossible to replicate and are cross-referenced with the original taggant data for lifecycle verification.
Certificate: Spectral Taggant and Encrypted Barcode
When the stone is graded, Microtrace applies a Spectral Taggant to the physical certificate and prints an encrypted barcode linked to the individual gemstone. This allows the certificate itself to be independently authenticated at retail.
Retail & Consumer Experience: Unified Authentication
Retailers and consumers validate both the certificate and the gemstone using a single secure mobile app and detector. The app verifies the taggant on the certificate, then checks that the barcode matches the laser mark on the stone. This dual confirmation verifies the relationship between the gemstone, its authenticated certificate, and the associated provenance and grading information.
A Complete, High-Security Solution
This turnkey system includes:
- Proprietary taggant chemistries for rough stone and certification
- Secure, laser-engraved micro-barcodes for polished stones
- Encrypted QR codes linked to blockchain or certification systems
- Mobile detectors and app for real-time field validation
Each component is engineered to function together as a unified, tamper-resistant solution from source to sale.
Trusted Partners in Provenance
This integrated solution is built on the combined expertise of Microtrace and PhotoScribe.
- Microtrace pioneered taggant-based authentication systems.
- PhotoScribe is the global leader in laser marking for gemstones.
This dual confirmation verifies the relationship between the gemstone, its authenticated certificate, and the associated provenance and grading information.
