The Gübelin Gem Lab team consists of highly qualified and experienced specialists. Each team member is trained specifically in his or her field of work, such as gemmology, the operation of analytical instruments, or gemstone photography.

On joining the Gübelin 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 Gübelin 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.

The Gübelin Gem Lab was founded in 1923 as a 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 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, gem traders, jewellers, royal families, and collectors globally who are looking for unbiased, independent and trustworthy opinions about their gems.
