Rose gold is an alloy created by combining pure gold with copper. This mixture of metals alters both the final color and the karat of the resulting product.
Composition of Rose Gold
The precise ratio of gold to copper determines the final shade and karat of the rose gold. Here's a look at the most common compositions:
- 18k Rose Gold: Typically, this alloy consists of 75% pure gold and 25% copper.
- This is the most frequently encountered rose gold composition.
- Other Karats: Different karat levels of rose gold are possible, with varying proportions of gold and copper.
- Lower karat rose gold may include additional metals to increase hardness.
Why Copper?
Copper is the key to creating rose gold's signature color. The more copper, the more pronounced the rosy hue:
- Color Modification: The addition of copper imparts a pinkish or reddish tinge to the normally yellow gold.
- Alloy Properties: Copper also influences the durability and strength of the gold alloy.
