Vintage .999 silver filagree Butterfly brooch/pin!‎

Helping my friend sell off her collection of jewelry. She got this particular brooch/pin while she was stationed in Italy many years ago. So I acid tested this piece because the markings on the pin part were kind of smooshed in there. I believe it says 999 which means that the pin is pure silver. It tests positive for sterling silver (acid test) but I believe it's pure silver. Anyway, the pin is about 1.15 long and .80 wide. Comes with it's original paperwork.
