Oxidised jewellery is metal jewellery with a deliberately darkened, grey-black surface, where the raised parts are polished back to show bright metal. The contrast makes engraved and embossed detail stand out, which is why the style suits tribal, boho and temple-inspired designs.
The term comes from oxidised silver, where silver is blackened with a sulphur-based solution. In the imitation market, most oxidised pieces are made from brass, copper or German silver and given a similar dark finish by chemical treatment or by plating.
How the finish is made
- Casting or stamping: the piece is made in brass, German silver or a zinc alloy, then cleaned and polished.
- Darkening: the piece is dipped in a chemical solution that turns the surface dark, or plated with a dark layer such as black or gunmetal plating.
- Highlighting: the high points are rubbed or brushed back so bright metal shows on the relief while the recesses stay dark.
- Sealing: a clear lacquer or e-coat is usually applied so the finish does not rub off on skin or clothes and does not keep changing.
Chemical oxidation or plating: why it matters
Chemical darkening sits in the metal surface itself. It gives a natural, uneven look that many buyers prefer, but it varies from batch to batch, and it can keep changing if the piece is not sealed.
Dark plating is more uniform and easier to repeat across a large order, but it can wear through at high points over time and reveal the yellow of brass underneath. Ask the maker which method they use and approve a sample made the same way as bulk.
What to specify on an order
- Base metal, for example brass or German silver, and whether the piece must be nickel-free for your market.
- Darkening method and target shade, with an approved reference sample kept by both sides.
- How much highlight you want on the relief, since this changes the look more than most buyers expect.
- Whether a protective lacquer is applied, and that it should not feel sticky or leave marks.
What this means for a buyer
Oxidised jewellery is one of the easier styles to order in volume, but shade consistency and base-metal choice cause most problems. German silver bases contain nickel, which matters if you sell in the EU. Our guide to common quality problems in imitation jewellery covers the defects to watch.
