HOW PURE IS YOUR GOLD?

The purity of gold is defined either in karats or fineness. A karat is 1/24 part of pure gold by weight, so 24-karat gold is pure gold. To find the percentage of gold in an object when the purity is stated in karats, multiply the number of karats by 100 and divide by 24.

24 karats = 100 percent gold

22 karats = 91.75 percent gold

21 karats = 87.5 percent gold

18 karats = 75 percent gold

14 karats = 58.5 percent gold

12 karats = 50.25 percent gold

10 karats = 42 percent gold

9 karats = 37.8 percent gold

8 karats = 33.75 percent gold
