Rose gold is primarily defined by its karatage, which indicates the percentage of pure gold alloyed with other metals, most notably copper. The different kinds of rose gold available are distinguished by this karat value and the resulting composition.
Different karats of rose gold offer varying shades of pinkish-red and levels of durability. The higher the copper content relative to gold, the more pronounced the rosy hue and the greater the metal's strength.
Common Types of Rose Gold by Karat
Based on the composition provided, the most common types of rose gold are:
- 18K Rose Gold: This karat has the highest percentage of gold among the common rose gold types.
- 14K Rose Gold: A popular choice, offering a good balance of durability and color.
- 10K Rose Gold: Contains the lowest percentage of gold among these types, making it the most durable but potentially having a less intense rose color or being prone to tarnishing.
Here is a breakdown of their typical compositions:
| Gold | Copper | |
|---|---|---|
| 18K Rose Gold | 75% | 22% to 23% |
| 14K Rose Gold | 58.3% | 31% to 33% |
| 10K Rose Gold | 41.7% | 37% to 39% |
While copper is the primary alloy responsible for the color, other metals like silver can also be present in smaller amounts, influencing the exact shade. The variations in copper content, even within a karat (like the range for 14K or 10K), can lead to slightly different appearances, from a subtle pink to a deeper reddish hue.
Understanding these different compositions helps in choosing the right type of rose gold for jewelry based on desired color, durability, and price point.
