Butterfly Silvertone Large Women's Statement Necklace Center Rhinestones Jewelry

Butterfly Silver tone Large Women's Statement Necklace Center Rhinestones Jewelry. Necklace was unworn but I took the tag off - still calling it pre-owned. Please see all photos for visible condition. This is a metal - not sure what kind. Age/brand unknown. Very unique! Hangs approximately 16 inches - see photo for measurement approximation. No missing rhinestones.
