The Provenance Proof


Today's customers have greater expectations when it comes to information about a gemstone's history. From the sourcing of raw materials, to the principals and values of the mines and companies behind the product, the value-chain as a whole has come under scrutiny. And yet, the conditions under which coloured gemstones are sourced are still highly opaque and lack independent verification. With this in mind the Gübelin Gem Lab has established its Provenance Proof initiative. It encompasses the development of an array of technologies with the aim of bringing more transparency to every step in the gemstone industry's value chain.

The Provenance Proof


The most recent addition to the Provenance Proof label is a blockchain project launched in partnership with Everledger, a leading global emerging technology enterprise.
The aim of the partnership is to create a digital ledger based on blockchain technology, which will enable the operations along a gemstone's value chain to be securely recorded, stored and shared.


Provenance Proof?

It is no longer good enough to provide information solely on the gemstone itself, such as physical attributes and the country of origin. Customers want to understand the whole value-chain. The Provenance Proof initiative and the technologies it encompasses, aim to provide a solution to these customer's concerns.

Traditionally, the Gübelin Gem Lab is an independent entity providing the gemstone trade with unbiased and neutral opinion on the identity, authenticity and origin of their goods, purely on the basis of scientific analyses and procedures. The new services offered under the Provenance Proof label are the logical continuation of their history of fostering trust in the gemstone industry.
