Transparency redefined.
Today's buyers have greater expectations when it comes to information about a gem's history. From the sourcing of raw materials, to the principles 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.
To give consumers the peace of mind they need, we aim to help all the gems and jewellery industry stakeholders by bringing transparency to their products through our cutting-edge tracing technologies.
Consumers get to see the lifetime journey of a gem from rough to a finished piece of jewellery.
A digital twin that mimics an actual gem itself can be created on the blockchain, allowing every stakeholder along the supply chain to add their story to the gem or the jewellery piece, eventually creating a streamlined overview for the end-consumers.
Learn moreThe Provenance Proof label was launched in parallel with the launch of the world's first Physical Tracers for emeralds that are DNA-based, nano-sized particles encoded with the mine's information to tackle issues revolving around a gem's origin.
Applied within the gem at the source, it allows identifying a gem's birthplace at a later stage, which we are proud to call the Emerald Paternity Test.
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.
The Gübelin Gem Lab is perfectly positioned to provide these services to the industry. Being part of the privately owned Swiss family business Gübelin founded in 1854, our firm has a long history of testing the most exceptional gemstones worldwide. Traditionally, we are 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. Our new services offered under the Provenance Proof label are the logical continuation of our history of fostering trust in the gemstone industry.
