What is Rhodium Plating?

As white gold can be grey in colour, it is common practice to rhodium plate white gold jewellery by an electrochemical process. It provides a bright, white, highly reflective and tarnish resistant coating, which greatly increases the life of the high polish on the gold.

How long will the pattern last?

This will depend on the pattern and the wear and tear due to lifestyle activities. Some rings can be re-engraved depending on the style and the age of the ring.
