nothing happens to gold when it comes in contact with mercury exept a physical change: the gold solves in mercury.
gold is a very neutral metal and will not take part in chemical reactions under normal conditions,so if you want to seprate gold from mercury all you need to do is to react the mixture with oxygen. the mercury will form the red powder like HgO(Mercury Oxide) but the gold will remain unchanged.

No, gold will always be gold. The Hg is reacting with other metals put into gold to make it harder. 24 K gold is seldom used, as it is too soft, and will scratch and bend. So they put in other metals to make it harder. Usually they use platinum or silver. Look up "gold", it will tell you what carats stand for, and give common names, like "white gold". Note: the jeweler is wrong, and does not understand.
