I just bought these earrings and noticed that the horseshoe-shaped post clasp on one was a tiny bit looser than I thought I should feel when putting them on (and compared to the other earring). I wore them anyway and sure enough, by the end of the day, the one with the loose clasp was GONE. An expensive loss. Macy's, please consider replacing this product with one that uses a more secure clasp. I've been a customer for years, but when I called to complain about the loss due to inferior workmanship, Macy's was unwilling to do anything about it. Very disappointing.
