About Gübelin Gem Lab:
For over 90 years, the Gübelin Gem Lab has been in the business of presenting unbiased and systematic observation and opinion on the nature and types of gemstones. To increase transparency within the industry, the company came up with the Provenance Proof.
The Provenance Proof covers a bundle of truly innovative and cutting-edge technologies such as The Emerald Paternity Test, which uses nanolabels to trace emeralds back to the exact mine; and the Provenance Proof Blockchain, the first digital ledger for coloured gemstones. These technologies are available for every stakeholder in the industry, from miners to end-consumers.
