To me, it largely depends on the goals of these school policies, and the nature of the item in question. Typically, policies such as this are aimed at things like helping keep student's focus on education rather than fashion, social standing, etc. Nothing about these typical goals is served by forcing a student to break their religious traditions.

In this particular case though, it's an issue of a piece of jewelry that little Sarika says is simply "important to her". It's not a piece of traditional garb that's required by her religion or anything like that. To me, that doesn't necessarily warrant changing the policy to suit her. If it being "important to her" is enough to justify it, then why can't another student wear jewelry that their father gave them as a gift because it's "important" to them, or that they inherited from a dead Grandmother because it's "important" to them, or a "lucky" ring or something because it's "important" to them?

That's my personal opinion on it.
