These amethyst costume earrings by Elsa Schiaparelli feature the single, large emerald-cut stones that were so popular in the 1940s. Although classic and classy, this pair of ear clips is really hard to photograph. The stones are open back (without any green, as the photos may suggest) in a silver-tone setting. The actual color is a deep, regal purple. Earrings like these never go out of style!
