Silvia of Florence creates this Murano glass necklace using the centuries old millefiori technique. Colored glass is heated, sliced, laid out in designs and precisely placed, forming unique mosaics, one piece at a time. Handcrafted exclusively for Uno Alla Volta, from the hearts and hands of artisans. Butterfly, heart and abstract charms range from approx. 0.5''- 0.75'' long. Made in Italy.
