Vintage 60s Zuni Sleeping Beauty Turquoise & silver double Tie Tack / Pin

I have literally Never seen anything like this, and I have been selling jewelry for 26 years, 16 of which was focused on Native American jewelry. The setting of the stones is 100% Zuni Pueblo, and the turquoise is Sleeping Beauty which is mainly what the Zuni folks use to make their pieces. Vintage circa the 1960s, so the silver and the stones both show heavy patina, which most collectors love to see and I recommend NEVER dipping turquoise as it can ruin the stones. The unique part (aside from the whole unusual piece) is that there are TWO thicker /longer tie tacks on the back. I'm not sure what the decision making process was in this but it's interesting. It would work well on a hatband or thicker shawl as well. 1.75 inches wide about .5 inches tall. No hallmarks, typical of vintage from this time period.
