Zuni Inlaid VNTG butterfly brooch

Beautiful large Sterling Silver Zuni butterfly brooch Inlaid with onyx, turquoise, mother of pearl and spiny oyster. This is a piece of Old Pawn jewelry purchased by me at a Native American auction in Phoenix in the mid 1990’s. In great pre worn condition with working clasp closure. There is a small crack in the right lower onyx piece visible on close inspection as seen best in the first photo.
