Due to the important safety measures installed in New York, we cannot operate our New York lab for the time being.

Read the latest update about the Gübelin Gem Lab and the measures we have taken to ensure our ongoing service.

The Gübelin Gem Lab has arranged special work arrangements for its laboratory in Hong Kong.

For the first time, large quantities of gemstones equipped with two innovative Provenance Proof technologies are available in the international trade. The combination of both a physical tracer and a digital ledger offers a completely new level of transparency.

The Gübelin Gem Lab is pleased to announce a collection centre in Shanghai and shuttle service to cope with the growing demand for Gübelin Gem Lab testing services in China.

The first blockchain for coloured gemstones – Provenance Proof Blockchain enables transparency for the entire gem and jewellery industry.

The first coloured gemstone blockchain, announced earlier this year, is taking shape. Initiated by the Gübelin Gem Lab, in cooperation with technology provider Everledger, the Provenance Proof Blockchain is a true industry solution, free for all, and open to every participant of the global gemstone and jewellery sector. 

The Gübelin Gem Lab and Everledger, a leading global emerging technology enterprise, have partnered to drive more transparency in the gemstone industry by creating the Provenance Proof Blockchain for coloured gemstones. 

At the JNA 2017 the Gübelin Gem Lab has been awarded in the category “Industry Innovation of the Year” for its Emerald Paternity Test.

Beginning September 1st 2017, the Gübelin Gem Lab offers the determination of the type of filler material in emeralds in order to provide more transparency.
