Vintage Sterling Necklace with Lg Pendant Beautiful Indian / Navajo 18.48 gr

  

It looks American Indian to me. Nothing like it comes up on google image search so it is a unique piece, and I suspect vintage. Marked Sterling on the back and on the clasp. The pendant is large and has some weight (see photo with quarter coin for scale).

The chain is very small and dainty. Overall weight is 18.48 grams. Sorry, no sales outside the US.
