1: Most of this situation cannot be returned. Instead, the diamond ring becomes yellow. Instead, the material of the diamond ring is 18K gold.
2: In order to make the diamond ring elegant and durable, the surface layer of the 18K gold ring is generally plated. However, in daily life, doing housework or cosmetics will cause the electroplating surface layer to wear or be corroded. The gold elements in 18K gold are analyzed by the gold ministry, especially in contact with mercury -containing cosmetics. It is the reason for the yellowing of the diamond ring. This is normal. It does not belong to the quality of jewelry. In order to avoid yellowing in daily life, you also need to maintain good wearing habits, reduce the contact of the diamond ring itself with the acid, alkali, salt, cosmetics, and sweat, and keep the diamond ring clean.
What should I do if I do not retreat?
