Because of the softness of pure (24k) gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties. Alloys with lower karat rating, typically 22k, 18k, 14k or 10k, contain higher percentages of copper or other base metals or silver or palladium in the alloy. Nickel is toxic, and its release from nickel white gold is controlled by legislation in Europe. Palladium gold alloys are more expensive than those using nickel. High karat white gold alloys are mor
