While both metals have a similar white, silvery finish, the difference between white gold and platinum is that each metal is made of a completely different mineral and alloy. White gold is created out of a composition of 75% pure gold, and 25% palladium. Platinum jewellery is made out of 95% platinum and 5% cobalt.
