What Is Anti-Tarnish Jewellery?
Everything that determines whether a piece of artificial jewellery lasts a year or a fortnight happens in four layers you will never see. Here is what they do.
Anti-tarnish jewellery is plated jewellery built with a barrier layer between the base metal and the outer plating, sealed under a protective coat. The barrier stops copper from the base metal migrating to the surface, which is what causes dullness, colour loss, and green marks on skin. Anti-tarnish pieces typically hold their finish for one to three years, compared with four to eight weeks for unbarriered fashion jewellery.
How a piece is built
Four layers, outside in. Tap any layer.
Four layers, built to keep their colour through everyday wear.
What tarnish actually is
Tarnish is corrosion. When copper or silver in a base metal meets oxygen, sulphur compounds in air, and the salts in sweat, it forms a new compound on the surface - copper oxide, copper sulphide, silver sulphide. That compound is a different colour from the metal underneath, which is why the piece goes dull, then dark.
It is a chemical change, not dirt. This matters because it means polishing does not fix it. Polishing removes the tarnished layer along with some of the metal, so each polish leaves less material behind. On plated jewellery, two or three aggressive polishes will go straight through the plating to the brass.
The only durable solution is to stop the reaction from starting, which is what a barrier layer does.
Common questions about anti-tarnish jewellery
What does anti-tarnish mean in jewellery?
Anti-tarnish means the piece has an engineered barrier that stops the base metal from reacting with oxygen, moisture, and skin acids. Tarnish is a chemical reaction, not dirt, so it cannot be polished away permanently once it starts. An anti-tarnish construction prevents the reaction rather than treating it afterwards.
How long does anti-tarnish jewellery last?
Well-made anti-tarnish jewellery holds its finish for one to three years of regular wear. Lifespan depends far more on exposure - chlorine, perfume, sweat, and humidity - than on how often you wear the piece.
Is anti-tarnish jewellery waterproof?
It is water-resistant, not waterproof. Hand-washing, rain, and sanitiser are fine. Swimming pools, sea water, and hot showers are not, because chlorine and salt attack the protective coat directly and heat opens the plating's pores.
Why does cheap jewellery turn skin green?
Copper in the base metal oxidises when it meets sweat and air, forming copper salts that transfer to skin as a green mark. It is harmless but looks permanent on light fabric. A palladium or nickel barrier between the core and the plating stops the copper reaching the surface, which is why barrier layers are the single most important part of the build.
Is anti-tarnish jewellery worth the extra cost?
If you wear a piece more than a few times, yes. A ₹300 unplated piece typically fades in four to eight weeks; a ₹1,200 anti-tarnish piece holds for a year or more. On a cost-per-wear basis the anti-tarnish piece is usually cheaper by the third month.
Does anti-tarnish jewellery contain nickel?
Some brands use nickel as the barrier layer because it is cheap and effective. We do not - nickel is the most common contact allergen in India, so our barrier is palladium-based.
How should I store anti-tarnish jewellery?
In a dry, closed pouch, away from other metal pieces. Humidity is the main enemy in Indian monsoon months; an anti-tarnish strip or a silica sachet in your jewellery box extends the life of every piece in it.
