Before I get into the description, I'd like to give a little back story on this piece.  This pin belonged to my great grandmother (I'm 70 years old).  This was given to her by her church in recognition of her teaching Sunday School for 50 years.  It's in great condition.  The top tip of the wing looked like a stone was missing, but I think the stone on the other side is just a little off.  I don't think anything is missing.  I've included some closeups of both tips so you can see it better.  I have not attempted to clean it.
