Hi,
Jewelers are supposed to have silver wire in their workshops, but being retailers they don`t. But they have modern minimalist sterling hook earrings. They are available online, too.
Straighten and insert it, cut with nail clipper leaving a millimeter on both sides.File the excess - filing will crate almost invisible irregularity at both ends thus fixing the wire, i.e. preventing its displacement.
It’s definitively ``do it yourself``..Good luck.
Regards
