The event featured a walk-through session for users to adopt the Provenance Proof Blockchain traceability system, presented by Mr. Klemens Link, Head of Development at Provenance Proof and the Gübelin Gem Lab, both companies are part of the House of Gübelin. Provenance Proof, an initiative from the House of Gübelin, creates services and technologies enabling and promoting more transparency to the entire gem and jewelry industry. The Provenance Proof Blockchain is one of these innovative technologies. The first blockchain for colored gemstones is a digital, tamper-proof logbook tracking the relevant data along the supply chain, from one owner to the next. It is open to any stakeholder of the gemstone and jewelry community who is ready to embrace transparency, and free of charge as costs are born by the Gübelin family.
