Sterling Vermeil Peruvian Demi-Parure Flea Market Find 2 Euro

I have not a clue how old this set might be. It came in a mid-century or older bracelet box, which I am sure is the wrong one for this set. I did test the metal and it is 100% 925 silver under the vermeil. The bracelet is missing 6 of the stones. I have no idea what kind of stone it is, either, but would like to replace them if possible. Doesn't strike me as being Turquoise. The design is that of a Sican tumi, with the stones set in the "blade". I am positive that the person who sold it to me thought it was costume jewelry. Nope!!

Thanks for stopping!
