Verdigris Patina Medium Heart Copper Earrings. The only way to describe these earrings is Sweet! The 3/4″ hammered copper hearts have a patina to look “aged”. Because of the process, no 2 earrings will completely match and will have color and design variations from yellow-green, olive, to turquoise shades. Pictures shown are representative of some of the variety. All earrings hang from handcrafted 100% 20 gauge copper ear wires.
