A long time ago I had a sterling earring of a thick snake with 2
halves that connected to look like it was going through your ear.
It had a post (of normal earring size) coming out of the front
half that was slightly curved. the back half had a hole in it
that curved with the shape of the earring. When you put them
together the curve created enough tension to hold them together.
And it worked because I wore these for years.
The only problem seems to be how to drill a curved hole (?). I
never quite figured that one out. But there’s got to be some
trick. As far a screw connection, you may run into problems,
tapping threads can be a pain and I don’t know the durability
with soft metal like silver, they might strip after a few uses
(just a guess). It may also be awkward for someone if they have
to turn the whole back half of the earring to get it on
Hey, here’s a thought: maybe you can drill a normal size post and
receiving hole but connect the two halves of the earring in a U
shape under the ear with a springy/tensioned hinge (like what
clip-on earrings have) and make the earring one piece that could
open to put on. Well it would be secure at least!
