An 18K gold chain is composed of 75% pure gold, with the remaining 25% made up of other metals like silver, copper, or nickel to enhance its strength and durability. The exact amount of gold in the chain will depend on its total weight; for example, if the chain weighs 20 grams, it would contain 15 grams of pure gold.
