Marketplace & Resale Platforms
Reduce risk and increase buyer confidence with independent verification.
Building trust, protecting authenticity, and enhancing buyer confidence in jewellery and luxury goods available on marketplace and resale platforms.
Online marketplace and resale platforms 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.
