Gold in its natural state is yellow.
In order for white gold to appear silver-like in color, it must be alloyed with other metals which turn the color into white tending to yellowish: for example, white gold 750 (18kt) is made of 750 parts of yellow pure gold and of 250 of other metals.
To make the gold extra white it must go through an additional process: the rhodium plating.
Therefore, the jewel undergoes a galvanic bath which turns its color extra white.
With the passing of time, the effect of the galvanic bath will fade away revealing its original yellowish color: in this case it will be enough to re-plate the jewelry every 12-18 months, so that it can maintain its luster and appearance.
To clean gold jewelry you will only need:
- A few drops of detergent
- A bowl of hot water
- A toothbrush with soft bristles
Cleaning gold is a very simple process: first, pour a few drops of detergent into the bowl of hot water.
Mix gently and let it soak for about 15/20 minutes. Then, you can use an old toothbrush with very soft bristles to gently brush the jewel or the gold item. At the end of the process rinse with lukewarm water with a soft tissue which will leave no residue on the object.
The white gold jewelry undergoes the same cleaning process but, as previously mentioned, it will need to be re-plated in the future.
