This is a unique wide butterfly choker necklace. It is not marked but did test as being made of sterling silver filigree. The choker has a large butterfly in the center with a florette or flower on either side. The necklace is designed to fit around the throat so that the butterfly is standing. The necklace measures 14-1/4 inches long and 1-7/8 inches at the widest point. The necklace is in very good condition but does have an age patina and could use additional polishing. The butterfly has been polished but the florettes have not. Please let me know if you have any questions. Thanks for stopping by.
