As pure gold is too soft for everyday wear, gold jewelry often also contains other metals, such as silver, copper, nickel or zinc, to make the piece more durable. The karatage shows how much of the metal is pure gold, compared to other metals. 24k is 100% gold, while 18k is 75% gold, and 14k is 58.3% gold.
