Gübelin Gem Lab
Welcome to the Gübelin Gem Lab
The Gübelin Gem Lab was founded in 1923 as a small gemmological laboratory to examine and determine the authenticity of the stones used in Gübelin’s jewellery. This was a way to maintain the trust of its clients and stay true to its ideals. Since then the Gübelin Gem Lab has grown to become one of the most respected institutions of its kind in the world. A completely independent subsidiary of the Gübelin Group, the Gübelin Gem Lab uses the latest science and state-of-the-art equipment to carry out its analyses. On the basis of this it issues its highly respected Gemmological Reports, which are relied upon by famous auction houses, royal families, jewellers, gem traders, and collectors globally who are looking for unbiased, independent and absolutely trustworthy opinions about their gems.
Gübelin Gem Lab Seal
Ever since its establishment almost a century ago, the Gübelin Gem Lab has been pursuing the highest possible quality standards and refrained from making any compromises regarding analytical infrastructure, level of education and staff know-how as well as internal regulations and processes. To warrant and perpetuate these outstanding quality standards, the Gübelin family has provided the Gübelin Gem Lab with its very own label the Gübelin Gem Lab Seal. It stands as a quality hallmark outlining a set of guidelines that must be followed in order for it to be included on a gemmological document. Learn more
We are proud to introduce to the gemstone industry the Emerald Paternity Test, a patented technology to prove the provenance of emeralds back to the exact mine. This novel technology uses DNA-based nanoparticles, applied directly at the mine on the rough crystals. This technology gives miners, governments, trade organisations, jewellery brands and final customers a tool to prove the very source of emeralds, instilling confidence and creating trust. The Emerald Paternity Test is the first of a series of technologies and services dedicated to bringing more transparency into the gemstone industry, united under our Provenance Proof label.

About Gem Lab
The Gubelin Gem Lab team consists of highly qualified and experienced specialists from seven different countries; between them they speak nine different languages – not forgetting “gemmology”, one of the languages they all have in common! Each team member is trained specifically in his or her field of work, such as gemmology, the operation of analytical instruments – even gemstone photography. Every gemmologist has a degree in an Earth Science (Geology, Mineralogy, Crystallography, Geography and so forth) complemented by a degree in Gemmology.
On joining the Gubelin Gem Lab team, our gemmologists complete an intensive two to three years’ internal training programme before reaching the level of expertise that enables them to append their signatures to a Gubelin report. We are proud of our expertise and our skills which, complemented with each individual’s unique personality, contribute to the strong core of our company.
