Overview
- The Sunday Times investigation prompted independent testing at the Birmingham Assay Office after Monday, and results showed extreme contamination such as a ring estimated to be more than 92% cadmium and a charm bracelet with roughly 3,300 times the UK limit.
- TikTok Shop banned the seller Perform Pearls and issued a recall after assay findings, and Amazon says it is investigating reported listings and removing affected items following customer reports.
- Cadmium is a toxic, carcinogenic heavy metal linked to kidney, lung and bone damage, and experts warn exposure should be minimised because risk rises if items are mouthed, swallowed or contact pierced or damaged skin.
- UK rules cap cadmium in any piece of jewellery at 0.01%, and regulators including the Office for Product Safety and Standards have intercepted and destroyed cadmium-heavy imports at the border, but enforcement depends on testing, trading standards and platform cooperation.
- The problem reflects long‑running supply‑chain gaps: past nonprofit testing since 2018 and recent seizures show repeated findings of high cadmium in low-cost jewellery and underscore uneven regulation in places such as the United States where federal adult-jewellery limits are lacking.
