Amazon pulled a $4 ‘sterling silver’ ring that was 92% cancer-causing cadmium. A jewelry expert warns it’s back

A British jewelry consultant is calling out Amazon—again.

“This is an utter joke,” Jayne Bond wrote in a Sept.

16 LinkedIn post , criticizing U.K. enforcement authorities after discovering that a ring with the same design as one previously exposed for containing dangerously high levels of cadmium was back on Amazon—this time offered by a different seller.

The £3.39 ring was advertised as “925 Sterling Silver,” which means it should contain 92.5% silver.

But Bond said preliminary testing of the ring she purchased detected cadmium, a toxic metal known to cause cancer.

Amazon told Fortune that the ring Bond identified in September has since been removed from its marketplace.

A ring that was 92% cadmium Bond’s discovery came two months after The Sunday Times published an investigation into jewelry sold through Amazon and TikTok Shop in the U.K.

Bond, who had spent months raising concerns with Amazon before alerting the newspaper, helped bring the issue to light.

The investigation found that a ring advertised on Amazon as 925 silver was an estimated 92.3% cadmium—more than 9,000 times the U.K.’s legal limit of 0.01% cadmium in jewelry.

Charms on a bracelet sold through TikTok Shop, also advertised as sterling silver, contained about 33% cadmium, roughly 3,300 times the limit, according to trade publication JCK’s summary of the report .

In July, Amazon said it was removing the affected products following an internal investigation.

TikTok Shop recalled the bracelet, notified buyers and said the seller, Perform Pearls, had been removed from the platform.

It isn’t the first time U.K. authorities have flagged cadmium in jewelry sold through Amazon.

In one Office for Product Safety and Standards notice , a silver-colored ring and earrings sold on the platform exceeded the legal cadmium limit, and Amazon removed the listing.
