Before and After Rhodium Plating


Rhodium plating is part of the family of Platinum, which means they are also a precious metal – considered the rarest and most valuable precious metal in the world. Rhodium is a silver-white metallic element that is highly reflective and resistant to corrosion.
Rhodium is also a very brittle metal, meaning rhodium plating alone can’t be used for manufacturing an Engagement Ring, Rhodium can easily crack and break, almost like glass.

However, Rhodium is prefect for plating jewelry. When plating jewelry with Rhodium, it enhances the durability of the metal which is plated with Rhodium.

2.) Is it necessary to plate my Engagement Ring?

Rhodium Plating is used to enhance the durability, luster and light reflection of a piece of jewelry.

Rhodium plating is used to get a more white finish that we all love, it also enhances the shine and brilliance of diamonds and moissanites.
Basically, Rhodium plating is a coating that enhances the entire look and durability of your Engagement Ring

Rhodium is plated using an electroplating process. For an Engagement Ring to be Rhodium Plated, it must first be thoroughly cleaned for the reason that if there is any dirt left on the Engagement ring, the rhodium plating will not hold.
Distilled water, steam cleaning and electro cleaning are some ways that the item is cleaned before it is dipped into the rhodium solution.  A positive electrical charge is then used to fuse the rhodium onto the base metal. Care must be taken, because if the electric current is too high, the rhodium plating will turn black. The process takes roughly around an hour and a half to be completed.
