It is a normal natural phenomenon for silver earrings to turn black, because the sulfur and oxides in the air and other natural media have a certain corrosive effect on silver. After wearing for a period of time, some tiny spots (silver sulfide film) will appear. , Over time, it will spread into pieces, or even become black. Therefore, silver earrings have some discoloration due to oxidation.
With the increase of wearing time, silver earrings will gradually become black, so we need to take good care of our exquisite silver earrings. Not only pay attention not to contact with chemicals during wearing, but also to isolate the air as much as possible in normal storage, and regularly clean the silver earrings.
