I'm making these earrings (much prettier in real life), but I'm having difficulty with the stringing. Momma, any suggestions? Or anyone else out there.....

The lower gem is a pendant with a horizontal hole. I originally thought that I could go through a vertical hole and just make the top into a loop and string on the earring piece.... but then, when arriving home, I realized the hole went the other way. Ugh.... I have thirty of these and the connection between the halo to the earring itself is the hard part.
