There is no disputing the growing preference for responsibly sourced gemstones. Yet until relatively recently, there was no reliable way to trace their journeys. Those patrons who sought to purchase pieces that were mindfully mined and marketed, were always left uncertain about the genuineness of claims of responsible sourcing. Another concern with regard to precious stones has been their authenticity. Despite certification and precautions during transfers from one owner to the next, there were cases of fraud.
Within this milieu, Gemfields, as a world-leading supplier of responsibly sourced coloured gemstones, has been developing innovative technology to eliminate these concerns. In partnership with the Gübelin Gem Lab, a state-of-the-art gemstone analysis laboratory, Gemfields has facilitated traceability along every stage of the value chain and provides seamless documentation. These technologies go a long way towards allaying the concerns of consumers who would like to be assured about the origins of gemstones they purchase and the sanctity of their journeys.
Traceability technology
In a game-changing breakthrough in the coloured gemstone industry, Gemfields has partnered with the Gübelin Gem Lab to adopt traceability technology, which creates independent proof of the provenance of emeralds. This test, called the Emerald Paternity Test, relies on customised DNA-based nanoparticles, infused into the natural fractures of emeralds, to trace them back to the exact place of mining. Taking into account the fact that an emerald undergoes various processes before reaching the end consumer, such as cleaning, cutting, polishing, transportation, setting, etc., the test has been developed specifically to survive all these. The nanoparticles can be retrieved and decoded at any stage along the supply chain.
From miners (both big corporates and cooperatives of small and artisanal miners) and governments to trade organisations, industry watchdogs, jewellery brands and final customers, this technology offers all stakeholders a completely new level of transparency when sourcing gemstones, instilling confidence and creating trust.
Digital and decentralised recordkeeping
In addition to the Paternity Test, another of Gübelin’s Provenance Proof technologies that Gemfields endorses and applies is Provenance Proof Blockchain. This technology enables security, along with transparency and traceability.
Based on a decentralized ledger, the Provenance Proof Blockchain allows all stages along the value chain to be traced, for any type of gemstone. The prime advantage of the blockchain is its high degree of security and seamless documentation of the data.
