How Does Gold Tarnish?
Tarnishing can be caused by air, moisture, perfume, sweat, lotions and household chemicals as these substances react with the gold in order to change or erode it's colour making it tarnished.
What Types of Gold Tarnish?
24k Gold
- 99.9% pure gold
- Extremely resistant to tarnish
- Rarely discolours
This is the least likely type to tarnish.
18k Gold
- 75% gold
- Mixed with stronger metals
- May develop slight dullness over time
Still very durable and high quality.
14k Gold
- Around 58% gold
- More alloy metals present
- More likely to tarnish than 18k or 24k
This is one of the most popular jewellery types because it balances durability and affordability.
10k Gold
- About 41% gold
- High alloy content
- Tarnishes more easily
It’s stronger, but less resistant to chemical reactions.
White Gold
White gold deserves special attention.
It’s usually coated with rhodium to create its bright silver appearance. Over time, that coating can wear away, causing:
- Yellowish tones
- Dullness
- Uneven colouring
Many people mistake this for tarnish.
Rose Gold
Rose gold contains copper, which means:
- It can darken slightly over time
- It may develop a warmer, deeper tone
Some people actually love this aged look.
Can Gold Bangles Tarnish?
Yes, gold bangles can tarnish. But whether they do depends on several factors.
Factors that affect tarnishing:
- Gold purity
- Frequency of wear
- Exposure to moisture
- Contact with chemicals
- Storage conditions
A gold bangle worn daily while showering, exercising, and applying perfume is far more likely to dull than one stored carefully.
Why bangles are especially vulnerable
Unlike necklaces or earrings, bangles constantly rub against:
- Skin
- Clothing
- Surfaces
- Lotions and soaps
That friction gradually wears down the surface.
Signs your gold bangle is tarnishing:
- Duller shine
- Dark spots
- Slight colour changes
- Uneven finish
The good news? Most tarnishing is temporary and fixable.
How to Clean Tarnished Gold
Before you panic and assume your jewellery is ruined, know this:
Most tarnished gold can look beautiful again with proper cleaning.
Simple at-home cleaning method
You’ll need:
- Warm water
- Mild dish soap
- A soft toothbrush
- A microfibre cloth
Steps:
- Mix warm water with a few drops of soap
- Soak the bangle for 15–20 minutes
- Gently brush away dirt and buildup
- Rinse thoroughly
- Dry completely with a soft cloth
That alone works wonders for many pieces.
What NOT to do
Avoid:
- Toothpaste
- Harsh chemicals
- Bleach
- Rough scrubbing pads
These can scratch or damage the surface.
Professional cleaning
If your bangle is heavily tarnished or contains gemstones, professional cleaning is the safest option.
Jewellers can:
- Polish the metal
- Restore shine
- Reapply coatings if needed
Many professionals recommend cleaning gold jewellery every 6–12 months if worn regularly.
Does Second Hand Gold Jewellery Tarnish Faster?
This is actually a really interesting question.
The answer is: sometimes.
Second hand gold jewellery can tarnish faster depending on:
- Age
- Previous care
- Existing wear on protective coatings
- Exposure history
Older jewellery often has worn surfaces
Over decades, tiny scratches build up. Those micro-abrasions make it easier for dirt and moisture to cling to the metal.
But vintage gold can also be better quality
Ironically, some older jewellery was made with:
- Higher gold content
- Better craftsmanship
- Thicker plating
So in some cases, vintage gold actually lasts longer than modern mass-produced pieces.
The biggest factor is maintenance
A well-maintained second hand gold bangle can outperform a poorly cared-for brand new one.
How to Prevent Gold Bangles from Tarnishing
Good habits make a huge difference.
Quick prevention tips:
- Remove bangles before swimming
- Avoid wearing them in the shower
- Keep them away from perfume and hairspray
- Store jewellery in dry, soft-lined boxes
- Use anti-tarnish pouches when possible
One simple habit most people forget:
Wipe your bangles after wearing them. so it gets rid of any sweat or moisture that may have gotten on the bangle.
Conclusion
So, can gold bangles tarnish?
Yes, they can. But it’s usually not the gold itself causing the issue. It’s the alloy metals mixed in to strengthen the jewellery.
The good news is that tarnishing doesn’t mean your jewellery is ruined. In most cases, it simply needs:
- Proper cleaning
- Better storage
- A little extra care
Some aging or tarnish however can make a piece have deeper tones and may appeal to people but still try to prevent it so you can make the most out of what you spent.
