Cheap "Silver" Jewelry on Amazon Found Loaded With Toxic Cadmium
Some of the cheap "silver" jewelry sold online isn't silver at all — and in some cases, it's carrying a cancer-causing metal instead. A recent investigation found jewelry listed on Amazon and TikTok Shop containing illegal, and in some cases shockingly high, levels of cadmium — a toxic heavy metal linked to cancer.
Under UK law, cadmium can't make up more than 0.01% of any piece of jewelry. One ring purchased on Amazon for £2.99, advertised as genuine 925 silver, blew past that limit by more than 9,000 times. Independent testing found the ring was actually 92.3% cadmium — nowhere close to the 92.5% silver content required for that label to be legally accurate.
Testing Turned Up More Than One Bad Actor
Investigators sent multiple pieces of jewelry to the Birmingham Assay Office, the authority responsible for verifying the purity of precious metals like gold, silver, and platinum. The results kept coming back troubling.
A charm bracelet sold on TikTok Shop by a seller called Perform Pearls, also marketed as 925 silver, tested at 33% cadmium — nearly 3,300 times the legal cap. TikTok Shop issued a recall after being alerted to the findings, confirming the seller had already been banned from the platform earlier this year for policy violations, with recall notices sent to the small number of customers who'd purchased the item.
Other sellers fared no better. A set of charms sold by an Amazon seller called GuiSaLa, marketed as "Tibetan Silver" and "999 silver," exceeded the legal cadmium limit threefold. A pair of earrings from a seller listed as TiantechKong, described as "metal alloy," blew past the limit by nearly 5,000 times.
Why Cadmium Is So Dangerous
Cadmium exposure can damage the liver, kidneys, and lungs, and is primarily linked to kidney cancer, according to Christer Hogstrand, a professor of molecular ecotoxicology at King's College London. He didn't mince words about the risk, comparing it directly to mercury and calling cadmium the more dangerous of the two.
Skin absorption risk is still considered limited, but the bigger danger comes from indirect exposure — cadmium residue transferring from jewelry to hands, and from there to food or the mouth. Dermatologist Ariel Haus, who specializes in skin cancer, flagged earrings as a particular concern, since they're often worn against pierced or already-damaged skin, and warned the real risk escalates sharply if a piece is mouthed or swallowed, especially by a child.
Regulators Are Struggling To Keep Up
This isn't an isolated find. Essex Trading Standards intercepted a batch of cadmium-contaminated earrings last February, and two separate product safety reports this year describe cadmium-laden jewelry being seized and destroyed at the UK border after arriving from Amazon sellers.
Kerry Saunders, operations director at Birmingham-based Domino Jewellery and a committee member of the National Association of Jewellers, didn't hold back on the state of oversight — arguing that UK trading standards simply lack the resources to keep pace with the volume of unsafe jewelry entering the market.
The regulatory framework itself spans three separate layers: the Hallmarking Act of 1973, which governs how precious metals are labeled; REACH regulations, which restrict hazardous chemicals in items with prolonged skin contact; and general product safety rules that apply to consumer goods broadly. Selling an item falsely labeled as a precious metal without proper hallmarking can actually constitute a criminal offense. Whether platforms like Amazon and TikTok Shop bear liability under those consumer safety rules remains murky.
One Buyer's Ring Stayed Listed For Months
Jewelry industry consultant Jayne Bond bought a £2.99 ring on Amazon labeled as 925 silver from a seller called The Construction People. Testing showed it was roughly 92.3% cadmium. Bond says she flagged the issue to Amazon back in May — but the listing stayed live. She reordered the same ring in July and got identical results.
One customer review on the listing described a severe allergic reaction that required medical treatment. Bond didn't hold back on her frustration, questioning why customer reviews flagging harm weren't enough to trigger action, and calling the inaction outright negligence. The ring has since been pulled from Amazon's UK site.
In response, Amazon said it takes customer safety seriously, noted it was reaching out to Bond directly about her experience, and said all products are required to meet applicable laws and platform policy — adding that the flagged items are now being removed following an internal review.
