Is it permissible to wear the popular Turkish blue evil eye bead, or hang it up, if it’s with the intention of an adornment, not with the intention that this will protect you? Some say this would be Shirk, or at least imitate those who believe in such Shirk. Any Fatwa of any scholar you are aware of?

As long as such things have only ornamental value in a society, it is no harm to use them but using such things on the basis of faith or believing that this can solve one’s problem is not allowed. We are not allowed believe in any kind of superstitions.
