Each sterling silver Star of David necklace is inlaid with a matrix of iridescent white opal by Leon Nussbaum, our London silversmith. Opal, considered ''the queen of gems,'' can flash patterns of color representing every hue of the rainbow as they flicker and change with every movement of the wearer. Believed by ancient peoples to actually contain fire, opal has long been ascribed many mystical and healing properties. This opal and sterling silver Star of David necklace is masterfully handcrafted exclusively for Uno Alla Volta, from the heart and hands of the artisan. Necklace measure approx. 18 inches long, with a 1 inch pendant and spring clasp.
