Limited Edition of 200 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. This sterling silver, square opal necklace is inlaid with a matrix of iridescent white opal by Leon Nussbaum, our London silversmith, and hallmarked for a guarantee of purity. Each square opal necklace, exclusive to Uno Alla Volta, will appear to flicker and change with every movement of the wearer. Limited edition of 200. Approx. 21in. long.
