These items are jewelry pieces composed primarily of gold alloyed with other metals. The designation “10 kt” indicates that the composition is 10 parts gold out of 24, or approximately 41.7% pure gold. The remaining percentage consists of other metals, such as silver, copper, zinc, or nickel, which are added to increase the durability and alter the color of the final product. For example, the presence of copper can give the item a rose-gold hue.
The use of lower karat gold offers a balance between affordability and precious metal content. The addition of other metals increases the hardness and resistance to scratching and bending, making it suitable for everyday wear. Throughout history, varying karat weights have been preferred based on cultural norms, economic factors, and the intended use of the jewelry. Alloys with lower gold content often provide more robust options.
