White Gold

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, so jewellry 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 jewellery, 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.
