Sterling and Turquoise Zuni Petit orders Point Pin

Gorgeous vintage Zuni petit point brooch. The brooch is a flower form that features 5 oblong cut stones and 10 round cut stones set in needle point bezels. Can be worn as a brooch or a pendant.
Is marked/scratched "BC Zuni" on the back. I think there might actually be an H in the center to, which would make it HBC
c 1960s - 1970s

Condition is excellent. There are no dents or orders dings. No missing or loose stones. Sadly, before it came into my possession, someone dipped it in sterling cleaner, ruining the oxidation and patina.

Measures 2" x 2"
