Ths Mexican Fire Opal necklace was handcrafted by Leon Nussbaum, our London silversmith, of pure British sterling silver. 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 leaf necklace is comprised of a 1.375 inch long pendant on an 18 inch sterling silver chain. Handcrafted for Uno Alla Volta from the heart and hands of the artisan.
