Patinaed Copper Bird Earrings (Genuine Copper) with Turquoise Colored Bead. An acrylic sealant has been applied to help maintain its beauty. I used a 20 ton press and a steel die to create the earrings. A steel textured plate was rolled onto the copper. Nickel free lever back ear wire. Earring approx. 3/4" H x 1" W.
