I believe this heart to be silver-plated. It had no markings, so it's hard to know for sure, but it tarnishes like silver and polished when I used silver polish on it, so I'm almost 100% certain. It's beautifully textured and measures 1 1/2" both ways. I've hung it on a bronze metal piece to which I've attached an antique black button, and to the center of the button, I added a silver flower-shaped bead. It has lots of moving bits attached at the bottom of the metal piece. Chain measures 24" and closes with a crab-claw closure in bronze color.
