Yes jewlery shoul be banned. One reason is because it can be distracting. Also becauseit can get lost. For example my friend had a shark tooth and it got lost. Another reason is because someone can steel it. The last reason is because someone can brag. For this reason jewlery should be banned from school.
One reason being is that jewelry should not banned because jewelry can be worn on everyday, not ever! I think that jewelry should in school because I personally think of all the others that want to wear jewelry, and someone says,"Oh, no, you can't wear that." Do you want jewelry to be in school or out? I'd say in school. What do think?
This depends on how safe the school is. If the school is known for violence and crimes then yes because the jewelry would get stolen. Otherwise, if the school is safe and and has a good reputation of people not having their things stolen then jewelry should not be banned.
