According to Gübelin Gem Lab, the gems contain a combination of Emerald Paternity Test and Provenance Proof Blockchain. Provenance Proof, an initiative from the Gübelin Gem Lab that moved on as an independent company recently, has developed both the Emerald Paternity Test, deploying physical tracers based on nano-sized tags, and the Provenance Proof Blockchain. All Provenance Proof technologies are available to the entire industry.
The Provenance Proof Blockchain is a digital, tamper-proof logbook tracking the relevant data of gemstones along the supply chain, from one owner to the next. This technology, developed with Everledger, is the only existing solution in the gemstone and jewellery industry, according to Gübelin Gem Lab.
These traceable gems will eventually become available to jewellery brands and retailers, offering an unprecedented level of transparency into the journey of a gemstone, and opening new ways of customised storytelling to retailers.
