vintage clip back clip on earrings lot, silver tone jet black bead rhinestone witchy dangle earrings

Lot of two different pairs of clip on earrings, both silver tone with jet black (glass, I think?). One with 'rhinestones', one with faceted look beads, both sets in good usable condition. Clean, no missing beads, backs look like they work fine. I did not see any makers marks on either of these sets. Vintage jewelry isn't something I know much about, but I thought these were pretty!
