When you buy gold jewelry, it isn't pure gold. Your gold is really an alloy, or mixture of metals. The purity or fineness of gold in the jewelry is indicated by its karat number. 24 karat (24K or 24 kt) gold is as pure as gold for jewelry gets. 24K gold is also called fine gold and it is greater than 99.7% pure gold. Proof gold is even finer, with over 99.95% purity, but it is only used for standardization purposes and is not available for jewelry.
So, what are the metals that are alloyed with gold? Gold will form alloys with most metals, but for jewelry, the most common alloying metals are silver, copper, and zinc. However, other metals may be added, especially to make colored gold.

Don't Quit
When things go wrong as they sometimes will;
When the road you're trudging seems all uphill;
When the funds are low, and the debts are high;
And you want to smile, but you have to sigh;
When care is pressing you down a bit
Rest if you must, but don't you quit.
Success is failure turned inside out;
The silver tint of the clouds of doubt;
And you can never tell how close you are;
It may be near when it seems afar.
So, stick to the fight when you're hardest hit
It's when things go wrong that you mustn't quit.

My will shall shape the future. Whether I fail or succeed shall be no man's doing but my own. I am the force; I can clear any obstacle before me or I can be lost in the maze. My choice; my responsibility; win or lose, only I hold the key to my destiny – Elaine Maxwell
