Question: What metal is added to yellow gold to make rose gold?
Show answer
Copper.
Rose gold is made by alloying yellow gold with copper. The copper gives the gold its rose color. The specific amount of copper used can vary and this results in varying shades of rose gold. The more copper that is used, the redder the gold will appear. A common mix for rose gold is 75% gold and 25% copper. This would result in 18 karat rose gold.
