There’s something quietly powerful about oxidized sterling silver jewelry. The rich dark patina, almost like soft charcoal, has a story all its own. At AgJc, we use a controlled oxidation process to create this effect, then seal it with a protective wax that allows the finish to soften over time. It’s not static. It lives, it evolves, it becomes more you with every passing day.
Just like a favorite leather journal or a well-worn linen shirt, this kind of silver grows more beautiful the more you wear it. Underneath the shadows, a gentle silver glow begins to peek through, revealing the movement of time and touch. It’s this subtle transformation that makes oxidized silver so personal—and so beloved.
How to Care for Oxidized Silver
Because each piece carries a delicate patina, a little extra love helps preserve its magic:
-Avoid rubbing or scratching the surface.
-Store your jewelry separately, away from abrasive materials.
-Clean gently with a soft, dry cloth. Avoid chemical cleaners or polishing cloths that contain abrasives.
