What is Rose Gold?

Gold in its original form is naturally yellow – therefore, to create other hues, such as rose gold, the yellow gold metal is alloyed with different elements to change the color. To obtain a beautiful, rich rose color, yellow gold is alloyed with copper, silver and sometimes zinc. However, it still is as strong and wearable as any other color gold, and the color will not wear off.
