Antique dragon/bird (?) earrings help please!

Hello and thank you all for your knowledge and expertise! I am wondering if anyone can help me with any information about these earrings. The stones are an amber/orange color until held up to the light, then they appear more or a light amber/yellow (please see photos). there is some kind of critter on top which looks like some kind of bird or dragon. No makers mark that I can see unless I am missing it somehow. Thank you very much with your help with these interesting earrings!

 

Those are very nice. 1920s or 30s, I'd think Bohemian. Might be a winged serpent but dragon is closer.

 

I guess it could be phoenix, given the orange/fire colored stone

 

The image/symbol is an "ouroboros"

Ourobouros isn't winged, that is. And the thing isn't eating it's own tail.
