To support our clients in an even faster and convenient manner, the Gübelin Gem Lab offers mobile laboratory service at various locations all over the world. This fully equipped analytical unit allows mainly testing for coloured gemstones directly at locations such as international trade fairs, or at client’s locations anywhere in the world. The mobile setup mirrors the capabilities of the permanent laboratories, ensuring comparable scientific standards and data quality. 

By bringing advanced Gemmological instrumentation near to our clients, OPT services facilitate swift and efficient testing, without the cost and inconvenience of shipping goods abroad. OPT services offer a faster turnaround time, without having to pay an additional fee for express testing. To find out the upcoming OPT events, see below and sign-up to the Gübelin Gem Lab Newsletter.
