Anti tarnish jewelry is treated or engineered with special metals (like stainless steel alloys) and molecular-bonded coatings (such as rhodium or nano-films) to block moisture, air and sulfur compounds from reacting with the metal surface. In addition, jewelry made of brass is naturally anti tarnish.

Coatings create a protective barrier that prevents oxygen and pollutants from reaching the underlying metal, while certain alloys inherently resist corrosion due to their chromium or rhodium content.

Longevity varies by treatment: rhodium-plating typically lasts 1–2 years under normal wear (and due care!), whereas high-grade stainless steel alloys can remain tarnish-free indefinitely.

Simply wipe pieces with a soft, dry cloth after wear, avoid harsh chemicals or abrasive cleaners, and store in air-tight or anti-tarnish pouches to extend the coating’s life. You can also read more on our webpage Jewelry Care.

Yes - properly coated pieces are water- and sweat-resistant, so everyday activities like swimming or showering won’t compromise their shine.

Most anti-tarnish items are nickel-free and hypoallergenic, eliminating the green discoloration or irritation common with lower-grade metals.

When the barrier thins, light re-coating or professional re-plating will restore full protection; many brands offer warranty or discounted services to refresh your pieces.
