The warm, reddish hue of rose gold, a popular gold and copper alloy used for specialist jewellery, makes it highly sought-after. In addition, rose gold is often referred to as red gold, pink gold, and occasionally as Russian gold due to its prominence in Russia in the mid-1800s. For instance, the amount of copper in red, rose, and pink gold differs from one another. Moreover, the red tint of gold is more obvious the more copper there is in it. Apparently, pure copper is reddish, and pure gold is a rich, deep yellow. In short, depending on each particular piece’s makeup, rose gold has a tint anywhere between the two.
