Why does silver become darker the more you wear it

We are all familiar with gold and silver jewelry. Sometimes silver becomes darker the more you wear it, and many people don’t know why. This is mainly related to personal physique. Because silver comes into contact with the skin more often, people’s skin will secrete sweat and other substances, which adhere to the surface of silver, so it feels like it becomes darker the more you wear it. In fact, this is a surface phenomenon and it will return to its original brightness through cleaning. Let’s take a closer look at why silver becomes darker the more you wear it.

1. Because everyone's endocrine and physical conditions are different, some people's sweat contains more acid, some contains less, and some people's body fluids contain higher sulfur content. These are substances that cause the surface of silver jewelry to turn black, so everyone will have different results when wearing silver jewelry. Some people will wear it as bright as new after wearing it for half a year.

2. Sulfur, nitric acid and oxides in the air and other substances (such as eggs and cosmetics) have a certain corrosive effect on silver. When silver jewelry is worn for a long time, sulfur and silver will combine to form a black silver sulfide film on the surface of the silver jewelry. It will appear as some tiny spots at first, and then spread into pieces, forming what people usually call silver scale. It turns black and affects the surface gloss of the silver jewelry. People usually mistakenly think it is discoloration.

Because of these natural properties of silver, silver has a good health-care effect. Wearing it regularly can neutralize toxic substances in the human body. Silver ions have a strong bactericidal effect and can kill 650 kinds of germs. They can be used as a poison testing tool and are very beneficial to the human body. It can also accelerate wound healing, prevent and treat infection, and purify water and preserve food. The ancients said: Wearing silver will bring you health and wealth, soothe your five internal organs, calm your mind, stop panic and eliminate evil spirits. Medically, it is much more effective for human health than other precious metals.
