A gold alloy designated as 14k contains 14 parts pure gold out of 24 total parts. The remaining 10 parts consist of other metals, such as silver, copper, zinc, and nickel. This composition influences the alloy’s color, durability, and cost, differentiating it from purer forms of gold like 24k gold, which is almost entirely pure gold.
The presence of these additional metals enhances the metal’s hardness and resistance to scratching and bending, making it more suitable for everyday wear in jewelry. This increased durability is a significant advantage over higher karat gold, which, while possessing a richer color and greater intrinsic value, is considerably softer and more prone to damage. The use of alloys in gold manufacturing has a long history, allowing for customization of properties to meet specific needs.
