Antique or Vintage Blue Bird Pins/Earrings

Not sure if these fall into a antique or vintage category but these are adorable and lovely!! They could also pass for earrings, I think they are pins looking at the post and the closures. Gorgeous blue color wings with diamond looking gems on the birds belly, looks to be gold as well. I’m unsure what the stones or the metal are exactly never had this item appraised or tested.
