Colored gold
Colored gold refers to various shades of gold that are created by alloying gold with other metals. These alloys can produce a range of colors, including white, rose, green, and blue gold. The different colors are achieved by varying the type and proportion of other metals mixed with the gold.
Types of Colored Gold[edit | edit source]
White Gold[edit | edit source]
White gold is an alloy of gold and at least one white metal, usually nickel, manganese, or palladium. The resulting alloy has a silvery appearance and is often used as a substitute for platinum in jewelry.
Rose Gold[edit | edit source]
Rose gold, also known as pink gold and red gold, is an alloy of gold and copper. The higher the copper content, the redder the gold appears. Common alloys include 18k rose gold, which is 75% gold and 25% copper, and 14k rose gold, which is 58.5% gold and 41.5% copper.
Green Gold[edit | edit source]
Green gold is created by alloying gold with silver and sometimes a small amount of copper. The resulting alloy has a greenish hue. This type of gold is less common and is often used in specialized jewelry pieces.
Blue Gold[edit | edit source]
Blue gold is an alloy of gold and indium or gallium. The resulting alloy has a bluish tint. Blue gold is relatively rare and is used in unique and custom jewelry designs.
Applications[edit | edit source]
Colored gold is primarily used in jewelry to provide a variety of aesthetic options. It is also used in watchmaking and other decorative arts. The different colors allow for creative designs and combinations, making colored gold a popular choice for custom and high-end pieces.
