All change metals also proportion the character of being capable of forming colored compounds mainly by anodizing. The technique consists of creating oxide layers of varying thickness and refractive similarities on the metal surface. This characterize is useful for making jewelry in myriad colors.
Palladium occurs in character in the ores of copper, nickel, gold and platinum & these ores are found in Canada, Australia, Africa, South & North America.

White gold is often prepared as an alloy of gold which has been decolorized by the addition of palladium.
