UL enters a formal collaboration with Gübelin Gem Lab.

As one of the world’s largest providers of supply chain auditing and monitoring services, UL is pleased to announce its formal collaboration with Gübelin Gem Lab supporting Gübelin’s ground-breaking technology, the Emerald Paternity Test.

Gübelin Gem Lab is an independent entity of the Gübelin group, founded in 1854, providing the gemstone industry with unbiased and neutral information on the identity, authenticity and origin of gemstones, purely on the basis of scientific analyses and procedures.

In 2017, Gübelin Gem Lab has developed the Emerald Paternity Test, a technology to prove the provenance of emeralds back to the exact mine of extraction. This novel technology uses DNA-based nanoparticles, applied directly at the mine on the rough crystals. The nanoparticles can be retrieved and decoded at any stage along the supply chain. This technology gives miners, governments, trade organizations, jewelry 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 the Provenance Proof label.

Within this exclusive collaboration, UL will verify the secure and correct application of Gübelin Gem Lab’s ground-breaking technology at each of the mining sites. UL provides a vast array of innovative services across the global jewelry, gemological and precious metals industries. This new collaboration between UL and Gübelin Gem Lab will further strengthen the confidence and trust that the global jewelry and gemological industries, gem trade, jewellery brands and end consumers can have in Gübelin Gem Lab’s Provenance Proof Label.

UL empowers trust in a complex world.
