Gübelin Gem Lab
The Gübelin Gem Lab is one of the world’s most respected gemmological laboratories, using the latest developments in science and state-of-the-art equipment to carry out its analyses. In our laboratories in Lucerne, Hong Kong and New York, we provide analyses of diamonds, coloured gemstones and pearls, and are particularly renowned for our expertise in coloured gems.
The Gübelin Gem Lab is also known for its research and its pioneering innovation. The Provenance Proof initiative is the umbrella brand of a bundle of technologies with the combined aim to bring transparency into the gemstone industry. The Emerald Paternity Test is a ground-breaking traceability technology enabling a truly independent proof of provenance, back to the exact mine. The Provenance Proof Blockchain creates a digital, decentralised logbook based on blockchain technology that records individual peer-to-peer transactions, creating a virtual ledger secured through cryptography.
