The Gübelin Gem Lab has launched a new service, called the Gem Passport, which is designed to accompany unmounted emeralds, rubies and blue sapphires of up to 3.00 ct with a genuine Gübelin Gem Lab document. The new service is aimed at addressing the trade’s reluctance to invest in gemmological reports from prestigious gem labs for certain stone sizes and more commercial qualities.

Gübelin said that Gem Passport was made possible due to the achievements of its deep-learning software Gemtelligence™, helping jewellery brands as well as retailers and increase trust.

The Gem Passport contains the main identification features of a gemstone, such as species and variety, country of origin and a simplified disclosure of the treatment status. It focuses on key features of the gem, which are determined by artificial intelligence. This shortens the testing workflow, in particular the labour-intensive microscopic assessment, and allows a lower pricing.

Daniel Nyfeler, Managing Director of the Gübelin Gem Lab, explains: “We believe that the Gem Passport is a highly attractive and affordable service for stones which so far were not accompanied by a testing document from a globally respected lab, giving peace of mind also to brands and retailers.”
