Black & green enameled round metal earrings

I have been lot's of research on unsigned jewelry, I got so much that I am overwhelmed, my brain can't deal with it anymore.
I know some designers didn't sign their pieces, anyone know if these are made by anybody special ?

Thank You

1980s, probably 1928 Co. Of little value, I'm afraid.

 

Agree on the era and that they have limited value. Just wanted to add a link to this page that has identified textures of earring backs for future reference.

Click on "1928 Jewelry Company" or "Identified Textures" to see the lists.

ETA: If they're not worth it to sell on their own, toss into a box for a jewelry lot to sell at a later date.

Okay Thanks, oh well

 

Okay cool, Thanks again

 

I agree - pretty but probably not by anyone in particular. I don't think they're as early as the 80s; the enamel is wrong.
