Very Unusual Earrings (?)

I am looking for any information about this set. They are (ostensibly) earrings but they're highly unusual, and I wouldn't be surprised if they were something ceremonial. I have spent over a year looking for information and so far five different experts have told me they were at a loss or it was outside their realm of experience. If anyone has seen anything like them please let me know! I doubt they're worth anything but I really want to find out something about them.

I bleach tested the metal part and I don't think it's silver but it certainly looks like it. The clear part is some sort of lucite/acrylic/plastic thing. If it weren't for that I would have put them pre-1940s. The filigree seems far too well done for a pair of throwaway plastic earrings. If this makes sense, they just feel old.

In any case, know nothing about them and would appreciate any feedback! They seem too large for jewelry, but no idea what else they could be.
