The Mexican Fire Opal leaf brooch was handcrafted by Leon Nussbaum, our London silversmith, and hand-set in pure British sterling silver. According to history, Mexican Opals were used by the Aztecs to adorn ornamental and ceremonial pieces. The secret combination of silica spheres within the opal creates a play of sparking light flashes, similar to flames from a fire, that will flicker with every movement of the wearer. Each brooch measures 1.75 inches wide by 2.25 inches high. Handcrafted for Uno Alla Volta from the heart and hands of the artisan. Click Here for more information regarding Fire Opal Jewelry.
