Help with maker on sterling earrings

Both stamps are poor and partial. Looks vaguely familiar.

 

Too long for me. Hurt when I run....

 

First thing that came to my mind was that it maybe said Peru and had the shape of the country? Yikes... *shrugs*

 

Pretty sure the last letter is I. Four letters. One almost looks like HOPI but on the other the O is almost certainly not an O.

 

These daylight pictures might be a little better

 

I suspect Peru. I've had their silver with an anvil mark and that looks similar.

 

This tag was on them. I can't make any sense of it.

 

Not any native american silver I've ever seen , & the tags are the sellers inventory numbers.
