Explanation:
- Rose gold is a metal that is made up of pure yellow gold mixed with other alloys like copper and silver.
- While pure gold is attractive, it is too soft to be used alone in bigger jewelry pieces, which is why it is combined for strength and longevity.
- Rose gold, often known as pink gold, is one of the most attractive, soft, and feminine gold jewelry options available.
Hence, rose gold is an alloy of pure gold and copper.
