What is rhodium plating in jewellery?

A rhodium plating is a process used in jewellery making to coat a piece of jewellery with a thin layer of rhodium, a precious metal belonging to the platinum group. This treatment is mainly applied to jewellery made of white gold o silver, with the aim of improve their appearance, increase their durability and protect them from wear and tear. The result is a very shiny and resistant silver-white finish, which adds elegance and sophistication to the piece.

Rhodium is one of the most expensive and exclusive metals in the world and is highly valued for its high melting point, hardness and corrosion resistance. That's why it's the perfect ally to keep your jewellery looking like new for longer.

How is rhodium plating done?

The process is carried out by electrolysis, a technique that uses an electric current to attach rhodium particles to the surface of the jewellery. Briefly, the procedure is as follows:

  1. Jewellery cleaning
    Before applying the rhodium plating, the part is thoroughly cleaned to remove any grease, dust or residues that may prevent proper adhesion.

  2. Preparation in chemical solution
    The jewellery is placed in a special solution containing rhodium salts.

  3. Application by electric current
    The jewellery is connected to one pole and a rhodium bar to the other, circulating an electric current so that the rhodium is deposited in the form uniform and very fine on the piece.

  4. Rinsing and final polishing
    After plating, the jewellery is cleaned and polished to intensify its shine.
