Sterling & 90% Coin Silver Eco Chic Textured Earrings. At Midnight Jo all of our jewelry is handmade using coins or flatware. These earrings measure about 5/8" in diameter (though they are not perfect circles). These earrings are a part of our Eco Chic collection which features earrings created from our leftover scraps from creating other jewelry. These earrings are made using 90% silver coin punch outs leftover from making our coin rings. All findings and ear wires are sterling silver. Stand out with these adorable earrings!
