These blue bead earrings by Hattie Carnegie are an imaginative example of the style that was so popular in the 1950s. They are formed by clusters of blue-glass beads in varying shapes, tones, sizes and finishes. The combination adds dimension to these ear clips. A few of the beads are iridescent because of their aurora borealis coating. Scroll down to see the Blue Glass Bead 2-strand Choker by the same designer. Both pieces are perfect for women who look best in cool colors.
