What Is Oxidised Silver? Everything You Should Know

Oxidised silver is genuine 925 sterling silver that's been deliberately darkened, usually by applying a sulphur-based solution or a controlled chemical reaction that speeds up the same tarnishing process silver does naturally over time. The recesses of a design darken first, while the raised, more polished surfaces stay bright, which is what gives oxidised jewellery its contrasted, antique look.

How is the dark finish actually created?

Jewellers apply a solution, often containing liver of sulphur or a similar sulphur compound, that reacts with the silver's surface and forms silver sulphide, the same dark compound that forms naturally as tarnish, just applied deliberately and controlled rather than left to happen slowly. The piece is then polished back so the raised, detailed areas catch light and stay bright, while the darkened recesses stay dark, creating depth that a plain polished piece doesn't have.

Is oxidised silver still real silver underneath?

Yes, entirely. The base metal is exactly the same 92.5% silver, 7.5% copper alloy as any other sterling silver piece, it's a surface treatment, not a different material. Learn more about the alloy itself in our guide to why oxidised jewellery blends tradition and style.

How is oxidised silver different from regular polished silver day to day?

Regular sterling silver is bright and reflective, and shows scratches and light tarnish more visibly against its shine. Oxidised silver is matte and dark, which actually hides small scratches and everyday wear far better, since there's no bright polished surface to show marks against. It suits ethnic, traditional and boho styling especially well, while polished silver tends to read as more modern and minimal. Neither is more "genuine" than the other; they're the same metal finished two different ways.

Does the oxidised finish wear off over time?

It can lighten gradually with regular wear and handling, especially on raised areas that get the most contact and friction. Most people find this natural fading adds to the antique character rather than detracting from it, though heavy or frequent polishing will strip the dark finish faster than normal wear ever would. If a piece has lightened more than you'd like, a jeweller can typically re-darken it using the same process used originally.

How do you care for oxidised silver without stripping the finish?

The single most important rule is to avoid aggressive polishing, since anything abrasive removes the dark layer along with any actual tarnish. Keep pieces dry and away from perfume, wipe gently with a soft cloth rather than a polishing cloth meant for bright silver, and store them the same way you would any sterling silver piece, in a dry pouch away from humidity. Our full silver care guide covers general cleaning, and our storage guide covers keeping pieces bright between wears.

What kinds of jewellery is oxidised silver typically used for?

It's especially common on jhumkas and other statement earrings, where the contrast shows off detailed patterns, as well as bangles, bracelets and pendants with traditional or ethnic motifs.

FAQs

Is oxidised silver real silver?
Yes, genuine oxidised jewellery is real 925 sterling silver with a deliberately darkened, antique finish applied to the surface.

Does oxidised silver fade?
With regular wear it can lighten gradually, but that natural change is usually seen as part of its antique charm rather than a flaw. A jeweller can re-darken it if needed.

Is oxidised silver good for daily wear?
Yes, the matte finish hides small scratches, making it more forgiving of everyday wear than bright polished silver.

How is the dark finish on oxidised silver created?
A sulphur-based solution reacts with the silver's surface to darken it, the same reaction that causes natural tarnish, just applied deliberately and then polished back for contrast.

Can I clean oxidised silver the same way as regular silver?
Not quite, avoid abrasive polishing or polishing cloths made for bright silver, since these will strip the dark finish. A soft cloth and gentle care work best.
