Opal has the ability to flash and array of luminous colors when exposed to light. Our London jeweler Leon brings us this brlliant collection; he hand-sets iridescent Mexican fire opal into British sterling silver to create this sparkling heart necklace. Handcrafted exclusively for Uno Alla Volta, from the hearts and hands of artisans. Approx. 18'' long, 1.5'' pendant, spring ring clasp.
