Screw back earrings stamped Peru. What is the image and how old?

Any idea one what this image is and how old they are. There is a tag that says sterling. Not sure where the mark is I haven't gone over it in totality yet.

Appears to be an Incan warrior. Screwbacks likely date them to the 1950s.

They say Peru on the back too, so Inca warrior is a good bet. It's crude enough to pass for a medieval European warrior, if need be.

 

Hi @Michelle Collins

Please use "all full size" for your images, thanks

 

Lovely, Michelle. It is shaped like a double spouted Moche vessel with a Moche warrior on it. The Moche were a pre-Columbian culture on Peru's north coast.
I'm with Debora on 1950s.

This is the shape:


Here is a single spouted one with a warrior, in this case a bird-warrior (condor?), but similarities in shield, club, helmet with neck-guard, etc:

 

Thank you!

 

Thanks everyone!

 

I still have to get more pics I don't see where the mark is for silver. Might be back!
