Pure gold is 24k...
"Carat (purity) or karat is a unit of purity for gold. In the United States, karat almost exclusively means the unit of purity. 24k is pure gold, 18k is 18 parts gold and 6 parts other metals (usually silver or copper), and 14k is 14 parts gold to 10 parts other metals. 10k is the minimum that can be sold as gold in the U.S."

Pure gold is 24 karats.
Hence 18k gold is (18/24) 75% gold and the othe 25% other metals.

24 k is pure gold also known as "Yellow gold"... not sold at purity in USA however, if you go to Dubai.. 24 is all you see.
supposebly 24 k is more softer than any other gold (such as 18, 14).

24. Any lesser number like 18 means 18/24 x 100% = 75%
