Sterling and Turquoise order Zuni Petit 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 order is excellent. There are no dents or 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"
