What is the difference between 18K white gold and platinum? (Also, what's "better"?)

The metals themselves look similar in that they are the same colour, although platinum gets shinier with time. The difference is that 18 whits gold is 75% real gold, mixed with severl other metals such as zinc or nickel and platinum is not gold at all. Platinum is a completely different type of metal. Is is also more expensive because of the fact that it is very durable and requires very little maintenance. White gold is often plated with a material called rhodium. It is often this colour that give white gold its "whitish" look. Unfortunately the rhodium does wear off making it in need of some restoration every few years. White gold is also not as strong as platinum, so people and particularly men who work in physical types of jobs often prefer platinum because it is much more durable.
