Health experts are warning shoppers after an investigation found dangerous levels of a cancer-linked heavy metal in jewellery sold through major online marketplaces, including Amazon and TikTok Shop. The findings raise fresh concerns about the safety checks applied to low-cost accessories sold online.

The report said a range of items, including earrings, rings and charms, were found to contain toxic levels of the substance. Experts reportedly highlighted earrings as an especially serious concern, underscoring the potential risk posed by products that are worn directly on the body.

The warning is likely to increase pressure on online retail platforms to more closely monitor third-party sellers and remove unsafe products more quickly. It also adds to broader concerns about how easily potentially harmful consumer goods can reach buyers through fast-moving digital marketplaces.

For consumers, the investigation serves as a reminder that cheap accessories sold online may not always meet expected safety standards. With questions now being raised over product oversight, the findings are likely to fuel calls for tougher enforcement and clearer protections for shoppers buying jewellery on the internet.
