FOCUS 焦点 14 | JNA March 2026 During the pandemic, a swab test became synonymous with health diagnostics, but Provenance Proof – an initiative by Gübelin Gem Lab – has redefined its purpose in the jewellery world. Swab tests are now used to recover physical tracers applied to diamonds for analysis at any point in the supply chain, revolutionising how the industry traces a gem's mine-to-market journey. Provenance Proof is conducting tests to see if swabbing works on emeralds while a pilot programme for application of physical tracers on other gems is underway. Meanwhile, Authentia.io, a patented, blockchain-based traceability solution founded by its CEO, diamond specialist Bruno Scarselli, is setting its sights on regions like Africa, where ethical sourcing is a pressing concern.
