Actually, the whole chapter is based on God taking away everything that they had placed their confidence in. He wanted them to fully trust and follow Him alone.
It's really not about jewelry at all. It is about where they had placed their confidence and derived their pleasure.
He takes away (
Isaiah 3:1-3): the stay and staff, whole stay of bread and water, the mighty man, man of war, the judge, the prophet, the prudent, the ancient, the captain of fifty, the honourable man, the counselor, the cunning artificer, the eloquent orator.
