Vintage LB Chavez Zuni Inlaid Stone Eagle Figural Brooch Pin

  

Vintage LB Chavez Zuni Inlaid Stone Eagle Brooch Pin. Quality craftsmanship and workmanship in this inlaid stone Zuni eagle.

Measures approx 2.5" tall by 2" wingspan. I've used a sunshine cloth to clean it up. There's a spot of discoloration on the back below the name that makes me think this might be a heavily plated item.

The metal tests as sterling but wonder if that mark is from acid eating through it? Unsure- this is how it came to me.
