Can a young girl wear earings that look like stars?
They are manufactured by the thousands by a company in China, are not used anywhere in the world today for idolatrous worship, and made as a trinket to be discarded after use.
Thank you for your time.
The earings may be worn. In our times when the stars are not commonly worshipped and it is being worn in a way that is clearly for jewelry, there is no prohibition against owning and using such items, only creating them yourself.
See Chochmas Adam 85:6, and Darchei Teshuva 141:18.
