Sterling silver tarnishes for a very unglamorous reason: it reacts with sulfur in the air. Yep, even your jewelry isn’t immune to a little everyday chemistry drama. Sterling silver is typically 92.5% pure silver mixed with 7.5% other metals—usually copper—because pure silver is just a bit too soft to survive real life. That copper toughens things up, but it also makes the metal more reactive. So, when your silver meets air that contains tiny amounts of sulfur (thanks, pollution, and even some natural sources), it forms a dark layer called silver sulfide. That’s the dull gray or black film you see—and no, your jewelry isn’t “going bad,” it’s just getting a little surface makeover.
Things like humidity, pollution, and everyday life—think skin oils, sweat, perfumes, and lotions—can speed up tarnishing. Ironically, though, the more you wear your silver, the less it tends to tarnish. (Turns out your skin helps keep it polished—who knew?) And unlike rust on iron, tarnish doesn’t eat away at the metal. It’s just a thin layer sitting on top, which is why a quick polish can bring back that shine like nothing ever happened.
If you’d rather not deal with the whole tarnish-and-polish cycle, storing your silver in a dry place—ideally in an anti-tarnish bag—can help slow things down. You might notice some pieces are labeled as rhodium plated, which is actually a nice bonus. Rhodium, one of the platinum group metals, acts like a protective shield, keeping your silver from reacting with sulfur in the first place and giving it that extra bright, mirror-like shine.
Of course, there’s a tiny catch (isn’t there always?). Rhodium plating is very thin, so over time—especially on rings or pieces you wear constantly—it can wear off. When that happens, the sterling silver underneath is back in the game and can start to tarnish again. In other words, rhodium doesn’t change how silver behaves—it just keeps it out of trouble for as long as that protective layer lasts.
