Anotations

Scope note:

The term for a class of white alloys used by jewelers as substitutes for platinum; it is easily manipulated into intricate shapes. The name does not convey the relative value of the different grades, which vary a great deal. Typical white gold alloys consist of 20 to 50% nickel with the rest being gold; zinc, silver, copper, platinum, and palladium may also be used.
