The purity of gold is measured in karats (symbol: k or kt). Pure gold (99.9% gold) is graded as 24k. Lower grades are represented proportionally; 14k gold is 58.5% gold and 41.5% alloy and 18k gold is 75% gold and 25% alloy. Gold is mixed with alloys to strengthen it, as pure gold is too soft for traditional jewelry.
