A white gold alloy composition consisting essentially of about 35 to 50 weight percent of gold, about 35 to 63 weight percent of silver, about 0.1 to 7 weight percent of a whitening component of zinc, germanium or both, and palladium in an amount of about 9 weight percent or less. The whitening component and the palladium are present in an amount sufficient to impart a white gold appearance and a liquidus temperature of no greater than about 1950 DEG F. to the alloy, preferably between about 1700 DEG and 1900 DEG F., and more preferably less than about 1850 DEG F. Thus, the preferred amount of palladium is about 2 to 5 weight percent and the preferred amount of the whitening component is about 0.5 to 6 weight percent.
