Vintage Florenza trembler fly pin. This item is a lovely trembler fly pin that has a very unique composition. The pin is made up of gold toned metal that has a black enameling over the antennae leading down to the head where a tiny round white glass cabochon with an aurora borealis like luster sits. From this point the wings spread out and are connected to the body by springs which tremble every time the pin is moved simulating flight by the fly. These wings have two interesting looking aurora borealis molded glass navette shaped gemstones that sit above two more tiny aurora borealis white glass cabochons. The main body section is composed of a tear drop shaped imitation pearl that looks gorgeous and makes up the front of this beautiful item. The back of this piece has a nice pin and clasp closure that holds well and the back of one of the wings is signed "Florenza". This pin measures 1" long by 1 5/8" in width and is in perfect condition having no missing or worn gemstones or metal. A lovely Florenza trembler fly pin.
