i heard don’t put extra jewelry on that one doesn’t normally wear every day. So in that case, even fashion jewelry wouldn’t be allowed even if its not gold/silver
if it is your minhag not to then you cant, the reason we dont wear gold or silver on Yom Kippur is not to “remind” Hashem of chet haigl using gold… so some women dont wear only gold, others wear little if its what they always wear….
