Knowra Colored gold Colored gold Colored gold is gold alloyed with other elements to produce hues such as rose, white, green, or blue. Its color depends on the alloy’s composition and, sometimes, its surface treatment.
Gold alloy : A metallic material made by combining gold with one or more other elements. Colored gold is produced by changing gold’s alloy composition.
Gold : A dense, corrosion-resistant chemical element prized for its luster and malleability. Gold is the base metal whose appearance alloying changes.
Rose gold : A gold-copper alloy whose reddish hue comes from its copper content. It is the best-known red-toned form of colored gold.
Yellow gold : Gold with a yellow appearance, commonly alloyed with silver and copper while retaining a gold-rich color. It provides the familiar baseline against which altered gold hues are judged.
Copper : A reddish chemical element used in electrical wiring, plumbing, and metal alloys. Copper gives gold alloys their characteristic rose and red hues.
Alloy : A material composed of a metal combined with one or more other elements. Colored gold belongs to the wider class of engineered metallic mixtures.
White gold : A gold alloy made pale by metals such as palladium or nickel, often finished with rhodium plating. It offers a light-colored alternative to silver or platinum jewelry.
Platinum : A dense, corrosion-resistant precious metal used in jewelry and industrial applications. It is a naturally pale jewelry metal, unlike alloy-whitened gold.
Silver : A lustrous, conductive chemical element used in jewelry, electronics, and coinage. Silver can lighten gold’s color and contribute to greenish alloys.
Metallic bonding : Chemical bonding in which delocalized electrons hold metal atoms together. Changes in metallic composition alter how an alloy reflects visible light.
