Most jewellery skin reactions in India are caused by nickel, not by brass or gold plating. Nickel is the leading cause of allergic contact dermatitis worldwide, and it is commonly used in cheap fashion jewellery either in the base alloy or as an under-plating layer beneath the gold finish. If a piece makes your skin itch, redden or break out in small bumps, nickel is the first thing to suspect.
Itching is not the same as a green mark
These are two different things and they get confused constantly. A green or grey mark on the skin is a harmless cosmetic stain, caused by copper in the alloy reacting with sweat and washing off with soap. An allergic reaction is a medical response: itching, redness, small raised bumps, sometimes flaking skin that appears hours after wearing and persists after the piece is removed. A stain is an annoyance. A reaction means your body is objecting to a specific metal, most often nickel.
Why nickel is so common in fashion jewellery
Nickel is cheap, hard and takes plating well, which is exactly why it ends up in inexpensive jewellery. It appears in two places. It can be alloyed into the base metal itself, or it can be used as a thin under-plate between the base and the decorative gold layer, because it helps the gold adhere and gives a brighter finish. The second case is the more frustrating one: a piece can look and behave perfectly for months, then start causing reactions once the top layer wears through and exposes the nickel underneath.
What to check before buying
- Does the brand state "nickel-free" explicitly, in writing? Vague terms are not a commitment.
- Does it name the actual base metal? A brand that says "brass" or "316L stainless steel" is telling you something; "alloy" is telling you nothing.
- Are earring posts specified separately? Posts sit in a piercing and are the highest-risk contact point of any piece.
- Is lead and cadmium mentioned too? Brands that have tested for one usually declare all three.
- Be cautious with "hypoallergenic" on its own. It is not a regulated term and carries no legal definition in India.
"Hypoallergenic" does not mean what most people assume
Hypoallergenic simply means "less likely to cause an allergic reaction". It is a comparative claim with no threshold behind it and no certification body enforcing it. A brand can print it on a piece that still contains nickel. This is why a specific statement — "nickel-free, lead-free, cadmium-free", naming the base metal — is worth far more than a general reassurance. Specificity is a claim a brand can be held to; hypoallergenic is not.
Which metals are genuinely low-risk
- Surgical steel (316L): very low nickel release, which is why it is used for medical implants and piercing jewellery.
- Titanium and niobium: biocompatible and among the safest options for freshly pierced or highly reactive skin.
- Nickel-free brass: safe for most people; the copper content can still leave a cosmetic green mark, which is a stain and not an allergy.
- Solid gold at 18k and above: low reactivity, though lower karats contain more alloy metals and more risk.
- Platinum: essentially non-reactive, and priced accordingly.
What Avirena uses
Avirena pieces are made from nickel-free, lead-free and cadmium-free brass with a protective anti-tarnish coating, and every earring post is surgical steel. We say this specifically rather than calling it hypoallergenic, because the specific claim is the one that is useful to you. To be equally clear about what this does not mean: brass contains copper, so a cosmetic green mark remains possible on some skin in hot or humid conditions. That is a stain, not an allergy, and our guide on brass and skin colour explains why it happens and how to avoid it.
If you have reacted to jewellery before
Start with a short wear test — a few hours rather than a full day — and check the skin underneath before wearing anything overnight. Keep pieces dry, since sweat and moisture increase metal release from any alloy. If you have had a confirmed nickel allergy diagnosed by a dermatologist, be aware that sensitivity can extend to trace amounts, and a patch test through a dermatologist is a more reliable guide than trial and error. Nothing in this guide is medical advice.
Common Questions
What jewellery is best for sensitive skin in India?
Look for pieces that state a specific composition rather than a general claim. Surgical steel (316L), titanium and niobium are the lowest-risk options, and nickel-free brass is safe for most people. The single most important factor is nickel, which causes most jewellery-related contact dermatitis. Check that the brand states "nickel-free" explicitly and names its base metal — vague terms like "alloy" or "hypoallergenic" are not commitments. Earring posts deserve separate attention, since they sit inside a piercing; surgical steel posts are the safer choice. In humid Indian conditions, keeping pieces dry matters too, because sweat increases metal release from any alloy.
Does nickel-free jewellery still turn skin green?
It can, and that is not an allergic reaction. A green mark comes from copper in the alloy reacting with sweat and moisture to form copper salts, which transfer harmlessly onto the skin and wash off with soap and water. Nickel-free simply means the alloy has no nickel in it, which addresses the allergy risk — itching, redness and raised bumps — but says nothing about copper. Brass contains copper by definition, so a nickel-free brass piece can still leave a stain while being entirely safe to wear. A protective coating prevents the copper contacting your skin, which is why coated pieces rarely mark until the coating wears.
Is "hypoallergenic" jewellery actually safe?
Not necessarily. Hypoallergenic means "less likely to cause a reaction" — it is a comparative term with no legal definition or certification behind it in India, and a piece labelled hypoallergenic can still contain nickel. It is more useful to look for specific statements: does the brand say "nickel-free, lead-free, cadmium-free"? Does it name the base metal? Does it specify what the earring posts are made from? A brand willing to state its composition precisely is making a claim it can be held to. A general reassurance is not.
