Most gold necklaces are made from a combination of gold and other metals to create an alloy, as pure gold is too soft for durable jewelry. Common alloys include 14k or 18k gold, which mix gold with metals like copper, silver, or zinc to enhance strength and durability while retaining the desired color and luster. The karat system indicates the purity of gold in the alloy, with 24k being pure gold.
