gold alloys
Jewelry-grade metal blends
Gold alloys are mixtures of gold with other metals—typically silver, copper, nickel, or zinc—to increase hardness, alter color, or reduce cost.
Pure gold is too soft for most jewelry and industrial uses, so alloys dominate: 14-karat gold is about 58% pure gold.
The karat system measures gold content, with 24 karats being pure.
Rose gold gets its pink hue from copper; white gold from nickel or palladium.
