Rose gold is an alloy of pure gold, copper, and sometimes a small amount of silver or zinc. The copper gives it its distinctive pinkish-red hue. The percentage of copper determines the intensity of the rose color. For example, 18K rose gold typically contains 75% pure gold and 25% copper (and sometimes other metals).

While rose gold does not tarnish in the traditional sense like silver, its copper content can react with certain chemicals or environments, potentially causing a slight darkening or deepening of its color over a very long period. This is often referred to as developing a "patina" and can be easily restored to its original luster with professional cleaning.

Periodic professional cleaning and inspection are also recommended.
