Sandcast NAVAJO Brooch - Sterling Silver

I found this the other day, mid-century Navajo sandcast sterling silver brooch. I try not to touch it much, I don't want to disturb that beautiful original patina, it part of its rough, rustic look that I really love. I found it at an estate sale for $2, and since I paid so little for it, I plan to keep it for my collection. I love Navajo jewelry!
