Gübelin Gem Lab launches Provenance Proof Blockchain

12 february 2019

At the AGTA Tucson gem show, the first coloured gemstone blockchain has been launched, which will track the provenance of gemstones – every step along the supply chain, gubelin.com writes.
The Provenance Proof Blockchain is a truly inclusive solution, applicable to any type of gemstone and open to any stakeholder of the gemstone and jewellery community who is ready to embrace transparency, and free of charge.
The purpose of the Provenance Proof Blockchain is to provide the industry with a tool that enables the tracking of each step of a specific gemstone along the supply chain.
Every transaction and hand-over adds an entry to the blockchain, resulting in a record, providing transparency into the complete journey of a gemstone, from the mine to the end consumer.
This ground-breaking blockchain project is part of the Provenance Proof initiative, a long-term programme established by the Gübelin Gem Lab to create services and technologies enabling and promoting more transparency in the gemstone industry. The Provenance Proof Blockchain is suitable for any type of gemstone.
All processes, including the registration and the upload of data, can be done with a smartphone. This ensures that the use of the Provenance Proof Blockchain is a truly inclusive solution, convenient for all types and sizes of stakeholders – artisanal miners, small-scale cooperatives, large companies, and any size of cutters and treaters, dealers, wholesalers, gem labs, manufacturers, jewellery brands, retailers, and end consumers.
There are no charges for the use of this blockchain solution. Both the data contribution and access are completely free of charge. Costs are born by the Gübelin family who is proud to make this contribution to foster transparency in the gemstone and jewellery industry in general.
Any professional stakeholder along the entire value chain is now invited to register and start using the Provenance Proof Blockchain.
