Mobile Laboratory
Off-Premises-Testing Services (OPT)

To support our clients more quickly and conveniently, the Gübelin Gem Lab offers a mobile laboratory service at various locations around the world. This fully equipped analytical unit is designed primarily for testing coloured gemstones directly at international trade fairs or client locations. The mobile setup mirrors the capabilities of our permanent laboratories, ensuring comparable scientific standards and data quality.

By bringing advanced gemmological instrumentation closer to our clients, our Off-Premises Testing services provide swift and efficient testing without the cost and inconvenience of shipping gemstones abroad. They also offer a faster turnaround time without an additional express testing fee.
