White gold (alloy with nickel, manganese, or palladium) is a homogeneous mixture because you can't see the separate substances that are in it. Therefore it is a homogeneous mixture.
Gold is metal that is a homogenous mixture. It is not a heterogeneous mixture, because a heterogeneous mixture can be physically separated.
