Why Does Jewelry Tarnish? (and what to do about it)

Have you ever bought a beautiful earring, necklace or bracelet and after wearing it a few times in the beach or in the summer, you notice it turning green? You’re not alone. Jewelry tarnish is one of the most common frustrations for affordable accessory lovers — especially in humid climates like Singapore.

The good news? Once you understand why jewelry tarnishes, you can easily prevent it — or skip the problem entirely with waterproof jewelry that never fades.

What Is Tarnish?

Tarnish is a chemical reaction that happens when metals react with air, moisture, sweat, beach water and chemicals in lotions and perfumes. Over time, these elements cause a thin, dark layer to form on the surface and crevices of your jewelry :(

Common Types of Tarnish

Not all tarnish is the same. Here are the most common types you might notice:

  1. Dark or dull film – usually seen on silver jewelry.

  2. Green discoloration – caused by copper reacting with sweat or moisture.

  3. Faded gold plating – gold-plated jewelry loses its layer with friction and exposure.

  4. Rust or pitting (tiny holes) – common in cheaper metal alloys that oxidize quickly.


Why Tarnish Happens Faster in Singapore

If you live anywhere near the equator, you’ve probably noticed jewelry tarnishing faster than usual. That’s because:

  • High humidity increases oxidation.

  • Sweat and salt air (especially near the beach) accelerate tarnish.

  • Sunscreen and lotion trap moisture against your skin.

Even expensive pieces aren’t safe from Singapore’s tropical climate — unless they’re made with tarnish-proof materials like the ones we sell here at Saltbourne.
