What is "Aurora"? Aurora beads are clear and sparkle in a full range of iridescent hues in different light. They result from the process of fusing two pieces of dichroic glass. Aurora colors are classified generally into warm (yellows, golds, oranges, and reds) and cool (greens, blues, and purples) although some glasses have BOTH warm and cool qualities. The Aurora pieces dramatically change color when they interact with light. An earring can appear nearly colorless at one angle but when turned to a lightsource, a magical play of brilliant blues, teals, purples, oranges, and pinks catch the eye.
