What causes silver bracelets to turn black?

Girls all love beauty, and every girl wants to have her own beautiful jewelry. Silver bracelets can not only decorate our appearance but also cure diseases! Ancient records show that the ancients knew that silver could accelerate wound healing, prevent infection, and calm the mind. Moreover, silver will turn black when it comes into contact with sulfur or arsenic, so the ancients used it to test for poison. Silver bracelets will behave differently when worn by different people. For some girls, the silver bracelet will become brighter and brighter, while for some girls, it will become darker and darker. This is not only related to the girls' original body excretions, but also to the things that the surrounding water sources come into contact with. So what are the reasons why silver turns black? Let’s take a look together!

1. Oxidation

Improper wearing or storage of silver jewelry, in a strong oxidizing environment, or contamination with strong oxidants will cause oxidation on the surface of the silver. If the silver bracelet is not worn frequently and is left alone after being taken off, the silver jewelry will combine with the sulfur dioxide in the air to undergo a natural oxidation reaction and turn black.

2. Pollution

When people are in a polluted environment where there are more acidic gases, hydrogen sulfide, nitric oxide and other compounds in the air, it can also cause silver jewelry to turn black.

3. Physical factors

As the human body is constantly metabolizing, toxins are eliminated. If the toxins are eliminated from the body and encounter silver, the silver will turn black. This also reflects that perhaps your health may not be very good recently and you should pay attention to your own examination.

4. The silver bracelet is made of poor quality

There are many types of silver jewelry, including Miao silver, Thai silver, Tibetan silver, snowflake silver, etc. Among them, the better one is snowflake silver. Secondly, the silver content of silver is divided into 990, 925, and 999. For example, 990 means that the silver content of this silver jewelry is 99%. Among them, the one we hear most is 925 silver. Silver with this silver content is mainly used to make necklaces, pendants, earrings, rings, etc. Silver bracelets are generally 999. Of course, there are also 990 bracelets, but they are less. Bracelets with high silver content and good material will generally not turn black when worn. Please note that this is generally the case, but there are special cases.

5. Endocrine structural reasons

Because everyone's endocrine structure is different, some people's sweat contains more acid, some contains less, and some has a higher ammonia content, so wearing silver jewelry produces different results. Acidic ones are easy to turn black, while non-acidic ones are not easy to turn black.
