Most gold necklaces are made of gold alloys, as pure gold (24 karat) is too soft for durable jewelry. Common alloys include a mix of gold with metals like copper, silver, or zinc, which enhance strength and durability. These alloys result in various gold purities, such as 18 karat (75% gold) or 14 karat (58.3% gold), balancing beauty and practicality.
