Sterling-stones cheapest Spider-web & fly pin

This large pin was one of my mothers interesting items. I can say that it is made with expertise with an open work design. Looks as if the spider has captured a fly ! Each critter has a natural bezel set stone and they are each set with marcasite stones, very well done. The item is stamped sterling and it looks to have a small logo with 2 letters, The item is in great condition and it looks great on . 2 1/2" by 3 1/4". cheapest
