The proof-of-concept project combines blockchain technology with Digital Product Passports (DPPs), offering unprecedented levels of transparency and trust for jewellery buyers and sellers.
At the heart of Hallmarking 2.0 is the integration of EAO’s hallmarking process with Everledger’s blockchain-powered Digital Product Passport. Alongside the traditional hallmark, each item receives a unique physical and digital identifier, creating an immutable, independently verified record of its journey from raw material to finished jewellery. At the point of sale, customers are given a QR code linking directly to their jewellery’s DPP.
By scanning the code, consumers can access detailed, verified information including:
Precious metal origins, with support for ethical sourcing standards such as Fairmined
Comprehensive gemstone and diamond certification from leading laboratories (GIA, Gübelin, GCAL, IGI)
High-resolution hallmark images and exact metal weights
Environmental and social responsibility disclosures from retailers
Product safety compliance details
The system also introduces major benefits for the trade, such as improved anti-counterfeiting protections, simplified resale, theft recovery, and blockchain-stored product attributes that enable automated insurance valuations.
The pilot project launches in partnership with London-based jeweller PureJewels by Bhanji Gokaldas, whose newly released Lotus Collection will be the first to feature Hallmarking 2.0.
“At PureJewels by Bhanji Gokaldas, we view hallmarking as more than a symbol of purity. It is a promise of provenance,” said Jayant Raniga, CEO of PureJewels. “Hallmarking 2.0 strengthens transparency, reinforces trust, and affirms the responsibility of our supply chains. It respects tradition while embracing innovation.”
Leanne Kemp, Founder and CEO of Everledger, added: “Digital Product Passports are transforming industries worldwide. Jewellery has a unique story to tell, and through Hallmarking 2.0, we are making that story visible and verifiable for every customer.”
Scott Walter, CEO and Assay Master of the Edinburgh Assay Office, emphasised the relevance for today’s buyers: “Hallmarking has always been about traceability and trust. In a digital marketplace where customers cannot physically check for a hallmark, Digital Product Passports provide transparent, secure provenance records. This helps consumers gain assurance that their jewellery is both genuinely hallmarked and responsibly sourced.”
EAO intends to expand beyond the initial proof-of-concept later in 2025, with the long-term goal of establishing Hallmarking 2.0 as a global benchmark for consumer trust and supply chain transparency in the jewellery sector.
