 Electrum was often referred to as "white gold" in ancient times, but could be more accurately described as "pale gold", as it is usually pale yellow or yellowish-white in colour.The modern use of the term "white gold" usually concerns gold alloyed with any one or a combination of nickel, silver, platinum and palladium to produce a silver-coloured gold.Electrum consists primarily of gold and silver but is sometimes found with traces of platinum, copper, and other metals.
