Are these vintage Hopi earrings?

Hi everyone,

I cam across this site when I was trying to search for more info on a pair of silver earrings I bought at a flea market a few years ago. I also asked ChatGPT and it says that they’re vintage Hopi earrings. However, I couldn’t find the hallmark on art.amerindien.com. It looks like two small cap “i”s. Any help is greatly appreciated!! Thank you in advance!!

I think that is supposed to be a rabbit track. I saw several in Hougart’s hallmark book but not one exactly like yours. Could also be antelope or deer.

Thank you for your reply. At least now I have a little more info! I love these earrings
