Is 925 Sterling Silver Hypoallergenic? The Honest Answer
Yes — for the vast majority of wearers, 925 sterling silver is genuinely hypoallergenic. The 92.5% pure silver and 7.5% copper alloy contains none of the metals (chiefly nickel) that drive most jewellery skin reactions. If you've previously reacted to costume jewellery and assumed all metals are off-limits, you'll likely find sterling silver perfectly comfortable.
That said, "hypoallergenic" doesn't mean zero risk. A small minority react to copper or to silver itself, and not every piece labelled "925" actually meets the standard. This guide cuts through the noise so you can wear silver with confidence.
Sterling Silver vs Other Common Metals — Quick Comparison
| Metal | Hypoallergenic? | Contains nickel? | Best for |
|---|---|---|---|
| 925 sterling silver | Yes (for most) | No | Everyday wear, sensitive skin |
| Surgical stainless steel | Yes | Trace amounts | Healing piercings |
| Implant-grade titanium | Yes — gold standard | No | Severe metal allergies |
| 18k+ solid gold | Yes | No (in 18k+) | Sensitive skin, fine jewellery |
| Silver-plated costume | No | Often yes | Avoid if sensitive |
| Nickel-plated brass | No | Yes | Avoid if sensitive |
What Does "925 Sterling Silver" Actually Mean?
The "925" hallmark is a guarantee of composition: 92.5% pure silver and 7.5% other metals — usually copper, occasionally zinc or germanium. Pure silver (999) is too soft for jewellery; the small copper addition gives sterling its strength without compromising hypoallergenic credentials. Genuine UK sterling silver carries a hallmark from one of the four UK assay offices (London, Birmingham, Sheffield, Edinburgh).
Our entire amber jewellery collection is set exclusively in 925 sterling silver, and we're a registered IAA Recommended Seller — so the metal underneath your stone is exactly what the hallmark says.
Why Sterling Silver Is Hypoallergenic for Most People
Roughly 10–15% of UK adults have a metal sensitivity, and over 80% of those reactions trace back to nickel. Sterling silver contains no nickel — that's the single biggest reason it's classed as hypoallergenic. Copper, the other 7.5%, is well-tolerated by the overwhelming majority of skin types. You're far more likely to react to the cheap nickel-plated earrings sold in fast-fashion shops than to a properly hallmarked sterling piece.
The Edge Cases — When Sterling Silver Might Not Suit You
Three groups should consider alternatives:
- Confirmed copper allergy: Rare, but real. If a dermatologist has patch-tested you positive for copper, the 7.5% copper in sterling can trigger a mild reaction.
- Argyria-prone individuals: Extremely rare. Long-term, heavy contact with silver compounds (not jewellery wear) can cause skin discolouration.
- Brand-new piercings: Most piercers recommend implant-grade titanium for the first 6–8 weeks of healing, then switching to sterling silver once the wound has closed.
If you fall into none of these groups, sterling silver is one of the safest fine-jewellery materials available.
Why Does Sterling Silver Sometimes Leave a Green Mark?
This catches a lot of first-time wearers off-guard. The faint green or grey mark that occasionally appears under a sterling ring isn't an allergic reaction — it's a chemical reaction between the copper in the alloy and the acids, salts and lotions on your skin. It's harmless, washes off with soap, and tends to happen more in hot weather, after exercise, or if you've applied perfume directly to the area. A clear nail-varnish coat on the inside of a ring is a popular workaround if it bothers you.
How to Spot Genuine 925 Sterling Silver Before You Buy
- Look for the hallmark. Genuine sterling carries "925" stamped somewhere — usually inside a ring band, on a pendant bail, or on an earring post.
- Check the assay mark on UK pieces sold for over £7.78 (sterling silver) — required by law.
- Test with a magnet. Sterling silver isn't magnetic. If your "silver" piece sticks to a fridge magnet, the base is iron or nickel-plated steel.
- Buy from a registered seller. Authority bodies like the International Amber Association and the UK assay offices vet members rigorously.
Caring for Sterling Silver to Keep It Comfortable
- Take it off before swimming — chlorine accelerates tarnish and can irritate skin.
- Apply perfume, sunscreen and body lotion before putting jewellery on.
- Store pieces in a dry, airtight pouch when you're not wearing them — air exposure accelerates tarnish.
- Polish gently with a sterling-silver cloth every few weeks. Tarnish itself isn't harmful, but a clean piece sits more comfortably on skin.
- If you'd like a deeper clean, see our at-home cleaning guide.

Frequently Asked Questions
Is sterling silver hypoallergenic for sensitive ears?
Yes — once piercings have fully healed. For brand-new piercings, most piercers recommend implant-grade titanium for the first 6–8 weeks, then transitioning to 925 sterling silver for everyday wear.
Can people with nickel allergies wear sterling silver?
Yes. Genuine 925 sterling silver contains no nickel — only silver and copper. Always buy from a hallmarked or IAA-registered source, as some cheaper imports add nickel to cut costs.
Is sterling silver safe for kids?
Yes for older children once piercings are healed. For infants and toddlers, jewellery in general is a choking and wear hazard — speak to your GP before introducing any earring.
Will sterling silver tarnish on my skin?
Sterling silver tarnishes with air exposure regardless of skin contact. The copper in the alloy can react with acidic skin and leave a temporary green mark, which washes off and is not an allergic reaction.
Is plated silver also hypoallergenic?
Not reliably. Silver-plated jewellery has a thin layer of silver over a base metal — often brass or nickel-plated steel. Once the plating wears, the base metal contacts skin and can trigger a reaction. Solid 925 sterling has no such risk.
The Bottom Line
If you have sensitive skin, a nickel allergy, or have simply been burned by costume jewellery in the past, 925 sterling silver is one of the safest materials you can choose. Buy from a registered seller, look for the hallmark, and care for it properly — it'll wear comfortably for years.
