What’s the Difference Between 14k and 18k Gold?

Today I’m going to try to answer a question that I’m asked very often. What is the difference between 14 karat and 18 karat gold? And the difference is that the 18 karat contains more pure gold. 75 percent of the gold in 18 karats is pure, 25 percent is alloy, and in 14 karats there is 58 and a half parts of pure gold and 41 and a half parts of alloy.
