Episode 8: Paths to Provenance with Daniel Nyfeler of Gübelin Gem Lab

Daniel Nyfeler - Managing Director, Gübelin Gem Lab

Despite recent efforts by the jewelry industry to address transparency and tracing issues across the global supply chain, the conditions under which colored gemstones are sourced remain highly opaque and lack reliable independent verification. 

In this episode, Daniel Nyfeler, Managing Director of Gübelin Gem Lab, discusses his company’s Provenance Proof initiative, aimed at developing new technologies to increase traceability and verify the origin and authenticity of colored gemstones. Nyfeler explains the first two Provenance Proof offerings: a blockchain for colored gemstones and the Emerald Paternity Test, a DNA-based technology to prove the provenance of emeralds back to the exact mine. He also shares how these technologies have been received by various industry segments, as well as the challenges and opportunities presented by increased transparency.
