I bought some silver beads to make anklets, and they changed color after wearing them for a few days. What happened?

Oxidized.

That's oxidation. Your diluted washing powder water and soft cloth need to be wiped again. There is also a saying that all silver jewelry will change color when it is in poor health, but it will change color in the air because the air is oxidized. Please wipe it and have a look. It is estimated to be 925 silver, and the other 7.5% of this silver is copper, but generally it will not appear yellow. It is estimated that the copper content exceeds 7.5%. However, the oxidation of 925 silver will also change color. As for what color it will turn into, it depends on the proportion of metal inside, and it will generally turn black.
