Filigree cheapest 900 Silver Peacock Vintage Brooch Large

Huge filigree silver peacock brooch with fine wire detailing.
No hallmarks, but tests positive for silver. These are usually 900 silver
but not positive.
Measures 3 5/8 inches across and 2 1/2 inches tall. Has the old
fashion C hook closure. Definitely could use a cleaning, but cheapest will
leave that up to the buyer.
