Marketplace & Resale platforms
Our experts are ready to help you find the perfect solution whether it’s hallmarking, analytical testing or valuations,
Building trust, protecting authenticity, and enhancing buyer confidence in resale jewellery and luxury goods
Online resale platforms and marketplaces are growing rapidly, from peer-to-peer sellers to global resale brands. Yet with this growth comes increased risk of counterfeits, product misrepresentation, and compliance failures, all of which damage customer trust and platform reputation.
At Birmingham Assay Office, we provide independent hallmarking, testing, authentication, and digital traceability services that help marketplaces and resale platforms protect their integrity, ensure compliance, and create a unique, trusted customer experience.
