Itching under your earrings, a rash where your watch strap sits, or dark patches under a ring or bangle: many people notice these but don’t realise it could be an allergy. In this video, Dr. Dipak Viradia explains why jewellery can cause itching and darkening of the skin, and what to do about it.

Why Jewellery Causes Allergy

The most common cause is nickel, a metal used in artificial (imitation) jewellery, cheaper gold and silver alloys, watch backs, belt buckles, jeans buttons, hair clips and spectacle frames. In sensitive people, nickel causes allergic contact dermatitis, an itchy skin reaction where the metal touches the skin. Sweat makes it worse, because it releases more nickel from the metal.

Once a person becomes sensitive to nickel, the allergy usually stays for life, but it can be well controlled by avoiding contact.

Signs of Jewellery (Nickel) Allergy

• Itching where the jewellery or metal touches the skin
• Redness, small bumps or a rash
• Dry, scaly or rough patches
• Blisters or oozing in more severe cases
• Common sites: earlobes, neck, wrists, fingers, and the navel area (jeans buttons, belt buckles)
• Symptoms usually appear 12–48 hours after contact, not immediately

Why the Skin Turns Black

Dark skin under jewellery can happen for two different reasons:

1. After allergy (post-inflammatory darkening). Repeated allergy, itching and scratching can leave dark patches that remain even after the rash settles. This is more common in Indian skin, and the patches fade slowly over weeks to months once contact is stopped.

2. Metal staining (not allergy). Some metals, especially copper and silver alloys, react with sweat, lotions or perfumes and leave a black or green stain on the skin. This stain washes off with soap and water and is not itchy. It’s harmless and isn’t an allergy.

Simple way to tell: if it itches and doesn’t wash off, it’s more likely allergy. If it washes off and doesn’t itch, it’s more likely metal staining.

How It’s Diagnosed

A patch test confirms nickel or other metal allergy. Small patches containing these substances are placed on the back and checked after 2 days or more.

What You Can Do

• Avoid nickel-containing jewellery. Choose nickel-free items, surgical stainless steel, titanium, platinum, or high-carat gold (22K/24K).
• Remove jewellery while sweating, exercising, bathing or sleeping.
• Cover metal parts that touch the skin, such as watch backs and jeans buttons. Clear nail polish on the inner surface can help temporarily.
• Don’t scratch, as it worsens darkening and can cause infection.
• Moisturise the affected skin regularly.
• Use creams only as prescribed. Avoid steroid or “fairness” creams bought without advice, as they can thin the skin and cause other problems.
• See a doctor if the rash spreads, oozes, becomes painful, or doesn’t improve after avoiding the jewellery.
