What is the correct solution for a Muslim woman residing in America to safeguard her jewelry, given that she fears its theft from her rented apartment, refuses to deposit it in a bank due to fees, wears it occasionally, and questions the benefit of insuring the apartment and its contents?

It is forbidden to deal with usurious banks and to deposit money in them. Commercial insurance is also forbidden, except in cases of necessity or compulsion. If you are compelled to deposit your jewelry and find no alternative other than the bank, then it is permissible for you to do so, with the obligation to cease dealing with them immediately once the necessity is no longer present.
