Vintage tie-bar or clasp with excellent grip.  About 1-3/4" in length and marked 925 / 18K on the back.  The artist used 18K gold for the llama and mounted it on .925 silver.  Probably Peruvian, considering the theme and design.  In the square panel immediately adjacent and West of the llama, we see possible initials but don't recognize the maker.

Estate item, slight oxidation, no damage.
