The term 'white gold' is used for the element Platinum. Best AnswerAsker's Choice

Most alloying metals to gold will tend to whiten the color and so it is possible to make carat golds that are white in color. White golds for jewellery were developed in the 1920's as a substitute for platinum.

White gold alloy compositions:

White golds are available up to 21 carat. There is no legal definition of what constitutes a white color in golds. Many commercial white golds are not a good white colour and are sometimes plated with rhodium to obtain a "white" color.

At the 9 carat (37.5% gold) level, a gold-silver alloy is quite white, ductile although soft and is used for jewellery purposes.

Nickel- and palladium-free 14-karat white gold alloy composition can consists of the parts by weight: about 58.34% gold, about 35-40% silver, about 0.5-1.80% tin, and about 0-0.75% germanium.

18-karat white gold alloy compositions are often 75% gold and 25% platinum or pallidium or 75% gold, 10% palladium, 10% nickel, and 5% zinc.
