What Is Hypoallergenic Jewellery? (And Why It Actually Matters for Sensitive Skin)

By Kataleya · Jewellery Education · 5 min read

If you’ve ever taken off a necklace because your neck started itching, or noticed a green ring where your bracelet sits, or broken out in a rash from earrings you genuinely loved — this one’s for you.

Skin reactions to jewellery are incredibly common, and for a long time many women just accepted it as their reality. But it doesn’t have to be. The rise of hypoallergenic jewellery has changed the game, and once you understand what it actually means, you’ll never go back to guessing.

Let’s break it all down.

So what does ‘hypoallergenic’ actually mean?

The word ‘hypoallergenic’ literally means less likely to cause an allergic reaction. In jewellery, it refers to pieces made from materials that don’t contain the common irritants that trigger skin reactions — most notably nickel.

Nickel is used in a huge number of cheap and mid-range pieces because it’s cheap, durable, and easy to work with. The problem? Nickel allergy is one of the most common contact allergies in the world. If your skin has ever reacted to jewellery, there’s a very good chance nickel was the culprit.

What causes jewellery skin reactions?

There are a few common triggers:

•       Nickel — the most frequent offender, found in many gold-plated pieces with base metals like brass or copper underneath

•       Copper — causes that green discolouration on skin

•       Zinc alloys (like pot metal) — often used in fast fashion jewellery

•       Low-quality plating that wears off quickly, exposing the reactive base metal beneath

 

The irony is that many pieces marketed as ‘gold’ are just gold-plated over these reactive metals. Once the plating thins or wears away — especially with water, sweat, or perfume — your skin is suddenly in direct contact with whatever’s underneath.

What materials are actually safe for sensitive skin?

Not all metals are equal. Here’s what genuinely works for reactive skin:

Surgical-grade stainless steel

This is the gold standard for hypoallergenic jewellery. Surgical-grade stainless steel (316L) is corrosion-resistant and releases very little nickel — the nickel it contains is locked tightly inside the alloy — so it is well tolerated by most sensitive skin. It’s also waterproof and tarnish-free, which means you can shower, swim, and sweat in it without any issues.

This is the base material in Kataleya’s gold plated pieces — because we know that a beautiful finish means nothing if it’s sitting on a material that irritates your skin.

Sterling silver (925)

Real sterling silver — marked 925, meaning 92.5% pure silver — is generally well-tolerated by sensitive skin. It’s the remaining 7.5% (usually copper) that can occasionally cause reactions in very sensitive individuals, though this is far less common than nickel reactions.

When shopping sterling silver, always look for the 925 hallmark. Anything without it may contain unknown alloys.

What to avoid

•       Brass-based pieces with thin gold plating

•       Pieces labelled ‘gold tone’ or ‘gold colour’ with no mention of the base metal

•       Very cheap fashion jewellery with no material information at all

•       Pieces that turn green — a telltale sign of copper or brass underneath

Does hypoallergenic mean the same as waterproof or tarnish-free?

Great question — and no, they’re not the same thing, though they often go hand in hand when the right materials are used.

 

When you choose jewellery made from surgical-grade stainless steel with quality PVD (Physical Vapour Deposition) plating, you tend to get all three. That’s the difference between truly wearable everyday jewellery and pieces you have to carefully manage.

How to shop for hypoallergenic jewellery — what to actually look for

Next time you’re browsing, here’s your checklist:

•       The base metal is clearly listed (look for stainless steel or 925 sterling silver, ideally backed by nickel release test results)

•       No vague terms like ‘alloy’, ‘metal’, or ‘gold tone’ without further detail

•       If gold plated, ask about the plating process — PVD plating lasts significantly longer than standard electroplating

•       Reviews mentioning sensitive skin or long-term wear without reactions are a good sign

•       A brand that’s transparent about their materials is one you can trust
