The reasons why sterling silver jewelry tends to turn yellow are as follows:

1. Silver is an active metal, which will turn yellow if it is not worn for a long time and exposed to air. (Ag (silver) oxidation: 4Ag+O2=2Ag2O.

2. Silver and gold can't be worn together, which will cause silver to turn yellow. Of course, even if you don't wear it at the same time, the silver jewelry will change color after a long time, whether it is electroplated or not.

3. Because silver reacts with sulfur in the air to produce silver sulfide of other colors, which greatly affects the beauty of silver ornaments.
