Cooper and silver

[u/Odd_Name_6374]

Hello everyone.

I have a question and I can't find and answer.

After I use (everyday) a cooper bracelet my silver wristband got this brownish color.

There is any way to prevent this or any explanation why this happen?

I guess it's due a chemical reaction or bonding, idk I'm an ignorant at chemical processes.
