These finishing techniques allow jewellers and manufacturers to enhance both the appearance and durability of silver jewellery. Our advanced galvanic processes ensure consistent quality, repeatable results, and complete safety for jewellery findings. At 925CRAFT, our experienced specialists use modern plating technologies to deliver professional decorative and protective finishes for sterling silver jewellery.

Silver Oxidation - Vintage Effect with Additional Protection

Silver oxidation is a chemical process that creates a thin layer of silver sulfide on the surface of the metal. This results in a darker, matte finish that gives jewellery a vintage, antique, or artistic appearance.

Oxidized silver is particularly popular in jewellery such as:

  • earrings

  • bracelets

  • necklaces

  • chains

  • rings

  • artistic and handmade jewellery pieces

This finish works especially well for retro, ethnic, artisan, and vintage-style jewellery collections.

Beyond aesthetics, oxidizing silver also provides additional protection by reducing oxidation and corrosion of the metal surface.

Minimum product batch weight for oxidation service: 50 g from model.

This solution is ideal for jewellery designers who want to achieve a deep patina effect while maintaining high durability and production quality.

Anti-Tarnish Coating – Modern Protection Against Silver Tarnishing

Anti-tarnish coating is a transparent polymer layer designed to protect silver jewellery from oxidation, moisture, air exposure, and other environmental factors responsible for tarnishing.

This coating can be applied:

  • to sterling silver (925)

  • to gold-plated jewellery

  • to rhodium-plated jewelry

  • to platinum-plated jewelry

  • to other galvanic coatings

Because the coating is completely transparent, it does not affect the color, texture, or shine of the jewellery surface.

As a result, jewelry maintains its brilliance for longer and requires less frequent cleaning.

Frequently Asked Questions (FAQ)

1What is oxidised silver?
Oxidized silver is silver that has been treated with a chemical process creating a darkened surface layer, giving the jewelry an antique or vintage look.
2Is silver oxidation permanent?
Oxidation can last for a long time but may naturally wear over time depending on usage. The patina can be refreshed if needed.
3Does oxidation change the purity of silver?
No. The oxidation method affects only the surface layer and does not change the metal purity or structure.
4What is best anti tarnish coating for jewelry?
Anti-tarnish coating is a transparent protective polymer layer that prevents silver from tarnishing due to oxidation or environmental exposure.
5Can anti-tarnish coating be applied to plated jewelry?
Yes. It can be applied to gold-plated, rhodium-plated, or platinum-plated jewelry to provide additional protection.
6Does anti-tarnish coating change the color of jewelry?
No. The coating is invisible and does not alter the appearance of the jewelry.
7How long does anti-tarnish protection last?
Durability depends on usage and storage conditions, but the coating typically protects jewelry for many months.
8Can oxidation and anti-tarnish coating be combined?
Yes. This combination is commonly used to maintain the oxidized color while protecting the surface from further oxidation and wear.
9Can jewelry with gemstones be oxidized?
In many cases jewelry with gemstones can be oxidized, but it depends on the type of stone and the construction of the product. Some delicate, porous, or heat-sensitive stones may require special care or may not be suitable for oxidation. Before the process begins, it is recommended to assess the jewelry individually to ensure that the oxidation treatment will not affect the stone or its setting.
10Should gloves be worn when handling oxidized jewelry?
Yes, it is recommended to wear gloves when handling oxidized jewelry, especially during production, polishing, finishing, or packaging. Gloves help prevent fingerprints, skin oils, and moisture from affecting the oxidized surface, which helps maintain the desired finish and overall appearance of the jewelry piece.
