YES!! All white gold is an alloy of pure 24ct yellow gold. ​Naturally, gold is a yellow colour and is mixed with other metals to create the beauty of white gold.Rhodium is then added as a final layer.

Rhodium is one of the elements listed on the Periodic Table Elements.

It is a very rare silvery-white metal. Rhodium actually holds the distinction of being the most expensive metal in the world!

However, Rhodium is an extremely brittle metal and as a result it isn't used to make jewellery. When used as a plating over other metals it can enhance the durability of the piece. 

Here are the steps needed to rhodium plate jewellery:

1. Polish the piece to bright finish.
2. Thoroughly clean the jewellery in an ultrasonic.
3. Rinse the jewellery using distilled water.
4. Steam off the piece. (using a jewellers steamer)
5. Electro clean: Set temperature at 120°F, 4 volts for 2 minutes in a glass beaker with a stainless steel anode, positive lead attached to the stainless anode, negative attached to the piece being plated. (Yes, this is a bit technical.)
6. Rinse in distilled water again.
7. Activator: Temperature at room temp, no voltage, for 30 seconds.
8. Rinse in distilled water again.
9. Dip in fresh distilled water.
10. Rhodium plate: At room temperature, 4.5 volts, for 20-30 seconds, negative lead attached to piece being plated, positive lead attached to platinized titanium anode.
11. Rinse in distilled water again.
12. Steam clean then dry off.
