Vintage Silver Filigree Butterfly Necklace VERY LARGE SALE

This is a large statement necklace of vintage  filigree handworked silver. Difficult to date but we feel does have some age to it.Unfortunately unmarked and hard  to test without spoiling the silver work but we feel it is definitely silver maybe of a lower grade.. A butterfly which we feel ybe originates from Persia or Turkey?. The butterfly is 2 1/2 ins wide and  2 1/2 in length at its longest part . No clasp just over the head. It does have a larger ring which is closed together. . This necklace has quality workmanship with small ball dangles hanging from the bottom. A long and heavy chain completes this item.
