I call these Moon Rocks because they really have the feeling of stones that came from the Moon... Or at least of rocks that were touched by a moonbeam and were transformed by it! These original Moon Rock Silver Earrings were designed with 20 mm Black Lava Rock puffed coin beads covered with a layer of pure silver (.999), and finished with sterling silver ball-end hooks. Very unique! Total length of earrings is 1-7/8 inches. Choose between 2 different styles: Moon Circles (with the fine silver on the edge of the stones); Moon Rounds (with the layer of fine silver on the center of the stones);
