Klemens is convinced that provable transparency and traceability empower trust, sustainability, and fairness in the entire gem and jewellery industry and that consumers have a well-founded interest in learning more about the story behind the jewellery they desire. 

In his vision, all stakeholders should be able to join the path of transparency, and Provenance Proof is a tool that allows them to access it. 

Klemens has an earth science background and is passionate about transforming technology-based visions into true-life applications. He previously headed the R&D in the Gübelin Gem Lab, one of the world’s most renowned gemstone laboratories. 

Today, Klemens leads Provenance Proof, an independent, young subsidiary of the House of Gübelin, dedicated to enabling proven and technology-based traceability of gemstones, diamonds, and jewellery items through the entire supply chain. Through his daily work with stakeholders worldwide, Klemens has developed a deep understanding of the challenges and opportunities of conducting business transparently.

About Provenance Proof

Provenance Proof enhances transparency and trust in the global gemstone and jewellery industry through innovative technologies. By integrating advanced DNA markers and secure blockchain technology, Provenance Proof provides unparalleled and provable traceability throughout the supply chain, from the rough gemstone to the finished jewellery piece. These technologies promote responsible sourcing and enhance customer trust and loyalty, helping brands meet modern expectations of transparency and sustainability. 

The DNA- based Provenance Proof Physical Tracers combat counterfeiting and fraudulent claims by embedding invisible, unique physical markers into gemstones or jewellery at any stage of the supply chain. These tracers ensure an indelible, verifiable physical link to the product’s origin, safeguarding brands from unauthorised replicas and strengthening consumer confidence.

The Provenance Proof Blockchain provides a secure, tamper-proof record of a gemstone’s journey. The underlying blockchain technology ensures the integrity of the stored information throughout the supply chain, which at the same time remains exclusive and private to the owner of the asset. With over 30 million gemstones and jewellery items recorded and more than 700 professional stakeholders registered, the Provenance Proof Blockchain has become an industry benchmark for transparency and accountability.
