The first coloured gemstone blockchain, announced earlier this year, is taking shape. Initiated by the Gübelin Gem Lab, in cooperation with technology provider Everledger, the Provenance Proof Blockchain is a true industry solution, free for all, and open to every participant of the global gemstone and jewellery sector.

Transparency is one of the hottest topics in the jewellery industry. 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. 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.

For the first time, large quantities of gemstones equipped with two innovative Provenance Proof technologies are available in the international trade. The combination of both a physical tracer (Emerald Paternity Test) and a digital ledger (Provenance Proof Blockchain) offers a completely new level of transparency.

A new milestone for traceable gems - Provenance Proof Marketplace makes access to transparently traded gems easier and more convenient.

Gemfields launches a series of NFTs to celebrate large emerald find, highlight transparency and traceability via Proof of Donation, and give back to charity.

The Gem and Jewelry Institute of Thailand (GIT) will participate at the Provenance Proof Advisory Board. With the GIT, we are welcoming a highly respected authority.
