NONE!!!!

Gold is an ELEMENT in its own right. It is NOT made up of two other elements.

However, in jewellery gold is a soft metal and is alloyed to base metals to make it hard wearing.

24 karat Gold is pure gold

Then you have 21 Karat, 18 Karat, and 9 Karat. each successively with a greater proportion of base metal , in order to make it 'harder wearing'.

The base metal can be copper, or nickel. Not iron.
