Opal, considered ''the queen of gems,'' can flash patterns of color representing every hue of the rainbow. Believed by ancient peoples to actually contain fire, opal has long been ascribed many mystical and healing properties.

These opal cross earrings will appear to flicker and change with every movement of the wearer. Earrings, accented with cubic zirconia, 1.5 inches long, wires. Exclusive to Uno Alla Volta.
