Diamond Provenance

Physical-marking technologies prove provenance for diamonds and gemstones for complete supply-chain security.

Total Solution from Gemstone Mine to Consumer

When it comes to precious gems, transparency is not only important when considering the clarity of a stone, but also in the journey it takes as it is mined, polished and sold.  Combined with blockchain technology, you can have a complete and transparent record of a gem from mine to market. A record that can identify diamond mines, confirm diamond authenticity and assure conflict-free provenance.

Taggant Technologies

Rough diamonds from a mine are marked with taggants—chemical tracers—resulting in unique identification of gemstones. These taggants are invisible-to-the-human-eye physical markings that are verified using a handheld reader and/or laboratory analysis.

Laser-Marked Barcodes

During the polishing process, taggant is removed and the gemstone is laser marked with a barcode. Your existing laser is already capable of marking gems, and with a software package, you’ll be seamlessly upgraded to the capability of marking impossible-to replicate 2D barcodes. At a retail location, the laser marking can provide sellers and buyers with the complete story of the stone.

High Security, Turn-Key Solution

The addition of our proprietary detectors and software to taggant technologies and laser-marked barcodes, results in a highly secure system that can’t be replicated or fooled. As a turn-key solution, using custom chemistries and laser marked barcodes, these gemstone and diamond provenance solutions can be integrated into the process you already have in place.
