These earrings are made with natural stone. The beauty of natural stone are the slight imperfections. Lovely blue stone earrings. The color variations in the blue stones add to the beauty of these natural gemstones. The 2 stone on top are separated by a small blue glass bead. I used silver plated wire and silver plated bead spacers. These earrings hang 2 inches long including ear wires. Perfect gift for yourself or someone special. Lightweight and perfect for everyday wear. Hypoallergenic and nickel free ear wires.
