Handcrafted by an artist in the mountains of North Carolina. Unsure of the kind of hammered metal. It does not tarnish. Black leather strands and the small amount of wrapping on the heart is black leather. Lobster claw closure. 9 hoops allow for adjustable lengths. Worn a couple of times. In excellent condition. I remember paying around $125 for it. I welcome reasonable offers. Thank you for taking a look!😊
