There is no such thing as naturally occurring white gold. White gold is yellow gold that has been alloyed with silver colored metals such as platinum, palladium, zinc, silver, or nickel. 14k white gold contains just as much gold as 14k yellow gold, it is just alloyed with a different mixture if metals. White gold is often plated with rhodium, to make it look more silver in color. White gold bands look good with cooler colored diamonds (colors D-J).
Pros
• Less expensive than platinum
• Will last a lifetime
Cons
• Polishing takes away some of the metal.
• Over time white gold plated with rhodium can begin to look yellow as it wears
