Vintage Silver Enormous Puffy Heart Pendant Chain Necklace 30"

Vintage Silver Enormous Puffy Heart Pendant Herringbone Curb Fancy Chain Necklace 30" Vintage silver huge puffed heart pendant necklace on extra long herringbone chain. Super unique and loud piece but also oh so cute! Likely sterling silver plated. It was super tarnished, which I was able to lift which suggests sterling silver, but only the clasp responds to magnets so it's not solid silver. The rest of the necklace does not respond to magnets. Stamped Korea but no material stamp. One side of heart has a little lightening as shown in pictures but not super noticeable. A really great piece! MEASUREMENTS Chain length: 30" Heart diameter: approximately 1.5"
