Combining metals to improve their strength or appearance is a longtime practice but not always do they combine to form such beautiful wearable art as this. The long bar earrings (2.5") are covered in gorgeous green patina, lightly polished, then wrapped with fine silver wire at the ends for contrast. The circle earrings (2") alternate between silver, gold, and patina all of which bring out the beauty in each other.
