How I care for my gold jewelry – and what I've been doing wrong for years

There's a myth about gold jewelry that I believed for a long time: that real gold takes care of itself. That you just put it on and you're done. That's not true. While real gold doesn't oxidize or tarnish, it does pick up dirt, gets coated by care products, and loses its shine without attention. Not dramatically, not quickly, but noticeably.

I'll tell you how I care for my own jewelry, what mistakes I made, and what really works.

First things first: What truly harms gold

Gold itself is chemically very stable – that's one of the main reasons it's so valuable as jewelry. But "stable" doesn't mean invulnerable. A few things attack gold jewelry, and some of them might surprise you.

Chlorine is its worst enemy. Indoor pools, hot tubs, sometimes even tap water with high chlorine content – these attack the alloy metals in gold. With 14K gold, where 41.5 percent of the alloy consists of copper, silver, and other metals, chlorine can cause discoloration over time and dull the surface. Taking off gold jewelry before swimming is not superstition; it's chemistry.

Perfume is more subtle, but just as real. Most fragrances contain alcohols and other compounds that can attack gold alloys over time. The rule is: perfume first, then jewelry. Not the other way around.

And hand cream. I wear my ring daily, and my hand cream left a slight residue on it over months, which dulled its shine. Not terrible, but noticeable if you know what to look for.

How I clean my jewelry – the simple method

I've searched for the perfect method for a long time. Ultrasonic cleaner, special cleaners, professional cleaning at the jeweler every few months. What I end up doing is so simple, I'm almost embarrassed to write it:

A small bowl with lukewarm water and a drop of dish soap. Put the jewelry in, let it soak for five to ten minutes. Then, gently brush the surface with an old, soft toothbrush – especially under settings and in small crevices where dirt tends to accumulate. Rinse with clear water. Pat dry with a soft cloth, don't rub.

I do this about once a month. Afterward, my necklace looks like new. Really. No special product, no expensive device. Water and dish soap.

What I no longer do: toothpaste. I used to do that because I read somewhere that it works. It's true – short-term. But toothpaste contains abrasives that scratch micro-fine lines into the surface. After a while, the piece looks duller, not shinier. Hands off.

What's different with gemstones

The dish soap method works well for pure gold jewelry. With stones, you have to differentiate, and that's something I only learned recently.

Hard stones like diamond, ruby, or sapphire – all above hardness 9 on the Mohs scale – are unproblematic. They survive the toothbrush without scratches and even benefit from it, as dirt is dislodged from under the setting.

But soft stones like moonstone, opal, coral, or mother-of-pearl are another story. These stones have a Mohs hardness below 6, some below 4. You'll scratch them immediately with a toothbrush. For jewelry with these stones: use a damp cloth, no brush, no soaking.

Pearls are particularly delicate. No cleaning agents, no ultrasound, no soaking. Just gently wipe with a damp cloth, right after wearing. Pearls react to sweat and pH changes, and regular gentle wiping significantly extends their lifespan.

Storage: The part almost no one thinks about

How you store jewelry makes a huge difference – especially for silver, but also for gold. The biggest sin I committed: throwing everything into one big bowl. Necklaces, rings, earrings all mixed up. The result: tangled chains, scratched stones, and rings with marks from other rings.

The solution isn't expensive. Every necklace needs its own space – hung up or individually in a pouch. Rings in separate compartments or on a ring stand. Earrings together, but not with other metal parts.

Silver jewelry is particularly sensitive to moisture and atmospheric sulfur. A small silica gel packet in the jewelry box – the little sachets you find in shoeboxes – is enough to significantly slow down tarnishing.

When you really need to go to a jeweler

Once a year, for daily worn jewelry. Not for cleaning, but for inspection. An experienced jeweler can see in two minutes if a setting is loose, if a joint shows cracks, or if a chain has a weak spot. Ignoring this can sometimes result in a lost stone, and that hurts – both emotionally and financially.

The jeweler will then also clean professionally – polish, rhodium-plate if necessary, check everything. This costs 20 to 50 Euros depending on the piece and is one of the most sensible investments for jewelry that means something to you.

With pieces from Corelune, you receive care instructions with every purchase – not as a text block, but specific to the material and stone of the piece. Because good jewelry deserves to be treated well.
