The imitation gold layer at the bottom is generally TiCN, which mainly increases the hardness and wear resistance of the rose gold.
The rose gold on the surface is formed by sputtering rose gold targets. There are some differences in the color of different rose gold targets, which can be roughly divided into the following categories:

3. 14K red gold, the gold content is 14K (58.33%), and other added metals are copper (41.67%).
