msneed took their answer straight from wikipedia off the internet. The one thing that needs to be mentioned is that pure gold is 24 karat, but 24 karat is too soft for most jewelry applications. Therefore most jewelry is either 10, 12, 14 or 18 karat. This means that most all gold jewelry is mixed with either Copper, nickel, zinc, and/or silver. White gold usually has much more silver and sometimes palladium or rhodium, therefore white gold is more expensive at the same weight as a normal gold item because white gold has more precious metals in its contents.

White gold refers to an alloy of gold and other white metals such as silver, palladium, or nickel. The natural colour of white gold is light grey and slightly yellow, so jewelry made of white gold is typically coated in highly reflective rhodium (sometimes coated in platinum and palladium), adding a more brilliant shine. Palladium and silver alloys are of higher quality than nickel and are sometimes not coated with rhodium. The purpose of plating is to add lustre to greyer jewelry, as well as to prevent oxidation of some of the metals found in the alloys. White gold is not platinum, but is used as a cheaper alternative, usually costing one-third as much as platinum.

As for buying - any reputable jewelry dealer should sell it.
