Would it be safe to wear my rolex/diamond ruby ring/yellow gold crucafix to school?

as i've said in previous questions i've never been to a public school but i'm going next year. so as my question says, would it be ok to wear my yacht master/red ruby diamond pinkie ring/gold crucifix/yellow gold bracelet to my new public school? its not a ghetto school, its small. maybe seven hundred. i've heard of Ipod getting stolen there because kids leave them in their backpacks or lockers but not pick pocketed or anything.
