The Bling That Fades: Why Gold Plated Jewellery Tarnishes
Let’s be real: gold plated jewellery looks stunning, costs a fraction of solid gold, and jazzes up your style nicely. But then, *cue dramatic pause*—why does it lose that glow and start to tarnish? Spoiler alert: it’s not magic, it’s chemistry. Let’s pull back the curtain and get into the nitty-gritty sneaky reasons your beloved gold plated pieces go dull and duller with time.
What Exactly Is Gold Plated Jewellery?
Before we unravel the tarnish mystery, a quick refresher: gold plated jewellery means a thin layer of gold—usually just a few microns thick—coats a base metal like brass, copper, or sometimes silver. This isn’t the same as solid gold or gold-filled jewellery, where the gold content and durability are dramatically higher. So, the thin gold coat is the star of the show but also the Achilles’ heel.
Why Tarnishing Happens: The Chemistry Behind the Fade
Tarnishing is just a fancy word for your jewellery losing that shiny, desirable luster and sometimes developing an ugly discoloration. But what’s causing it? Here are the main culprits, scientifically and practically:
1. The Thin Gold Layer Isn’t Invincible
Gold plating is delicate. That thin gold layer easily wears off with everyday wear—friction, rubbing, knocks, constant touching—all work overtime to chip away the gold. Once the gold disappears, the less glam base metal underneath is completely exposed and starts reacting with the environment.
2. Moisture Is No Friend
Sweat, water, humidity—our constant companions—are notorious tarnish triggers. When moisture creeps through tiny cracks or wears through that gold layer, it reacts with the base metals (like copper or brass), causing oxidation, the science-y process behind tarnish. So all that gym time, rainy days, or hand washing without care? Guilty of speeding up your jewellery’s dull phase.
3. Chemical Contact Accelerates the Drama
Perfumes, lotions, hairsprays, cleaning agents—these everyday chemical cocktails sneakily corrode the gold plated surface. Many of these contain acids or compounds that weaken the gold layer and expose the base metal beneath. The truth? Your beauty routine might be sabotaging your sparkle, according to Artizan Joyeria.
4. Skin Chemistry Plays a Part
If you have naturally acidic skin or sweat a lot, your gold plated jewellery might tarnish faster. The acids in sweat can react with the metal beneath the gold plating, causing dark spots and tarnishing. It’s personal chemistry that jewelry owners often overlook but cannot dodge.
5. Oxygen and Air Exposure: An Oxidation Party
Prolonged air exposure means constant oxygen contact. While pure gold resists oxidation, the base metals under the plating do not. When exposed, they oxidize and form that pesky dull, greenish, or black tarnish layer. It’s the boring but true sidekick to your jewellery’s slow decline noted by Austen Jewellers.
6. Friction and Physical Wear—and Tear
Throw in the gym bag, toss it on your desk, slide your wrist under a sleeve hundreds of times a day—the natural friction rubs down the plating. It’s like the gold layer is slipping off your jewelry piece bit by bit, exposing the base metal prime for tarnishing.
7. Storing With Other Metals? Not the Best Idea
Ever notice weird discolorations when jewellery pieces get cozy together? When different metals touch, chemical reactions can take place, speeding up tarnishing. So, that means avoid mixing your gold plated bracelet with silver rings in the same pouch.
8. Sunlight and Heat: They Aren’t Just for Plants
Extended sunlight and environmental heat exposure degrade the delicate plating, causing it to lose its smooth sheen and crack. So leaving your favourite piece baking on a sunny windowsill? Not a win.
How to Keep Your Gold Plated Jewellery Sparkling
Knowing why gold plating tarnishes is half the battle won. Here’s how to fight back and extend the life of your shiny treasures:
- Keep jewellery dry. Avoid wearing it in the shower, pool, or while exercising.
- Avoid contact with lotions, perfumes, hairsprays, and cleaning chemicals.
- Store pieces separately in soft pouches or dedicated jewellery boxes, like the Jewellery Box Collection or the elegant Wooden Jewel Box from Digirake to prevent metal-on-metal contact.
- Clean regularly but gently with a soft cloth and mild soap; avoid abrasive scrubbers.
- If you want to restore tarnished gold plated jewellery, look for suitable cleaning kits—like those recommended for India and for Global including USA—which are specifically made to be gentle on plated layers.
When You Should Rethink Gold Plated Jewellery
Gold plating is a fabulous option for affordable glamour, but if you want jewellery that holds up to rough wear or lasts decades, it may be better to invest in solid gold or gold-filled.
