If most earrings make your ears itch, redden or weep within a day, you have probably been told to buy better jewellery. That advice is only accidentally right. The problem is usually not price or quality. It is one specific metal, and it turns up in expensive pieces as readily as cheap ones.
Nickel is the most common contact allergen there is
Nickel allergy is the most frequently diagnosed contact allergy in North America and Europe, and it affects women considerably more often than men, largely because of pierced ears.
The reaction is contact dermatitis. Skin in contact with nickel becomes red, itchy and sometimes blistered or weeping. It can appear within hours or take a couple of days. Once sensitised, you stay sensitised: the allergy does not fade with exposure, and repeated contact tends to make reactions come faster.
The reason it shows up in jewellery so persistently is that nickel is genuinely useful. It is cheap, it is hard, it takes a good polish, and it makes other metals easier to work. So it ends up in alloys throughout the industry, including in places people assume are safe.
Where nickel hides
- Sterling silver. Sterling is 92.5 percent silver and 7.5 percent something else. That something else is usually copper, but nickel appears in some alloys.
- White gold. Gold is yellow. White gold is gold alloyed with a whitening metal, and nickel is one of the traditional choices. Palladium white gold is the alternative, and costs more.
- Under plating. Many plated pieces carry a nickel underlayer between the base metal and the gold, because it helps the gold adhere. As the plating thins with wear, that layer reaches skin. This is why a piece can be fine for a month and then start reacting.
- Cheap steel alloys. Not all stainless steel is the same. Some grades contain meaningful nickel.
That third one explains the most confusing pattern people report: an earring that was fine at first and became a problem later. Nothing changed about the alloy. The barrier over it wore through.
What hypoallergenic actually means
Not much, on its own. It is not a regulated term in most markets. Anyone can print it.
What is worth something is a specific claim about a specific metal. Nickel-free means the maker is telling you what is not in it. Surgical steel, implant grade, and a stated steel grade are all more informative than the word hypoallergenic by itself.
The practical test when reading a listing: does it name a material, or does it name a feeling? Nickel-free stainless steel is a material. Gentle on skin is a feeling.
Materials that are generally safe
- Nickel-free stainless steel. Durable, holds a finish, unbothered by water, and inexpensive enough for everyday pieces. The steel grade matters, so a maker who states nickel-free is telling you something real.
- Titanium and niobium. The safest options available and the usual recommendation for fresh piercings or severe reactions. Limited in styles and higher in price.
- Platinum. Very inert, very expensive.
- Solid gold, 14k or higher. Usually fine, with the caveat that white gold may be nickel-alloyed. Yellow gold is the safer bet.
A practical way to shop
- Look for the post material specifically. The post sits inside the piercing, in contact with broken skin. It matters more than the decorative part.
- Treat unspecified metal as nickel-bearing. If a listing says alloy or metal or gold tone and nothing else, assume the worst and move on.
- Be suspicious of plating alone. Plating is a barrier, and barriers wear. What is under it decides what your skin eventually meets.
- Watch the delayed reaction. If a piece is comfortable for weeks then turns uncomfortable, that is the signature of plating wearing through to a nickel layer.
- If reactions are severe, see a doctor. Patch testing identifies the allergen properly. This article is general information, not medical advice.
What we make this line from
Our Everyday earrings are 18k gold plating over premium stainless steel, and the steel is nickel-free. That combination is the point: the gold gives the colour, and the steel underneath is both what makes the piece waterproof and what makes it wearable for people who react to most jewellery.
Because the base metal is nickel-free rather than merely covered, the delayed reaction described above does not have a mechanism here. There is no nickel layer waiting under the gold to be reached.
Prices start at $22.99, shipped from Ontario to Canada and the United States.
