Why does the ring change color so easily?

Question: I bought a ring, and it showed up after wearing it for less than a week. Why is it so easy to change color? Answer: Rings are generally electroplated. Electroplating will make the ring look more beautiful and have more texture. However, the thickness of the plating and the quality of the craft directly affect the color retention period of the ring. At the same time, in order to ensure that the ring is not easy to change color, A protective layer'swimming' is added during electroplating. Your ring has changed color within one week. It is very likely that the plating layer is very thin and there is no 'swimming' protection. It is also possible that the ring has been manufactured for a long time and the color retention period has passed, so you will reveal the color after wearing it.
