Vintage inlaid butterfly pin

Is this Zuni? it looks older, plus has the 3 circles at top and “balls” on either side. approx. 1.75" high and 1.75" at widest at top.
No marks on back, but definitely silver (tarnished). Would appreciate any input. Thanks.

Definitely looks Zuni. Also, appears to have age, possibly 1950s. Thanks for sharing.
