Stainless steel jewelry after 6 months of daily wear: what showers, the sea, and sports do to it

Stainless steel jewelry after 6 months of everyday wear: What showering, the sea, and sports really do can be predicted with considerable accuracy. In short: The stainless steel itself remains unchanged; it doesn't tarnish or turn green. What shows after six months are fine scratches, a layer of limescale if you never rinse it, and, on gold-plated pieces, the first light spots on the clasp and the inside of the ring. Two minutes of care a month keeps it that way.

Most of the questions Corelune receives revolve around one point: What will the piece look like in six months? Photos from the first day don't help much. That's why here is what happens to stainless steel jewelry in 6 months, sorted by wear and tear and being honest about the gold plating.

Why stainless steel doesn't tarnish

Stainless steel contains at least 10.5 percent chromium. Chromium forms an invisible oxide layer on the surface that reseals itself after a scratch. Silver, on the other hand, reacts with sulfur from the air and skin and turns dark; brass reacts with sweat and turns the skin green. Corelune uses 304 and 316 stainless steel; the latter also contains molybdenum and withstands salt even better.

What can be seen after 6 months

The table shows where the line is drawn: not with water, but with friction. A 45 cm chain resting on the collarbone hardly rubs. A ring rubs constantly: a ring weighing around 5 g sits directly on the edge of the desk, while a 4 g stud earring barely touches anything. That's why gold-plated chains and stud earrings stay beautiful longer than gold-plated rings.

The 2 minutes that make the difference

After the sea or the swimming pool, hold it briefly under the tap and pat dry. Wash it once a month with lukewarm water and a drop of dish soap. Let perfume and cream sink in first, then put on the jewelry. That's all it needs; a detailed guide is available in Cleaning jewelry with household remedies. Which situations are still a reason to take it off, such as contact sports or weight training with a barbell, are explained in Jewelry during sports.

If you are looking for a piece you can put on in the morning and forget about in the evening, stainless steel is the right choice. For rings that rub against the keyboard every day, I would choose the silver-colored tone. For chains and earrings, there is no reason not to go for gold. The selection can be found under Waterproof jewelry; everything at Corelune is made of stainless steel.

Frequently asked questions

Can I take stainless steel jewelry into the sea?

Yes. 316 stainless steel withstands salt water particularly well, as does 304, if you briefly rinse the jewelry with fresh water afterward. Salt crystals that dry out are the only thing that causes issues: they make the surface look dull and rub against the gold plating.

Does chlorine water discolor gold-plated stainless steel?

The stainless steel itself does not react. The 2.5-micrometer gold layer remains stable with occasional swimming, but with daily training in a chlorine pool, it wears thin more quickly at rubbing areas. If you swim three times a week, you will have a more relaxed experience with silver-colored stainless steel.

Why does my stainless steel jewelry become dull?

It is usually a film of soap, limescale, and skin oil, not tarnishing. Lukewarm water, a drop of dish soap, and a soft cloth remove it in 2 minutes. It is better to avoid abrasive cleaners and toothpaste, as they leave fine scratches.
