Limited Edition of 150 Our San Francisco artisan creates this omega necklace; an artful tangle of gleaming silver-plated wire. Our sculptural piece, a limited edition of 150, is accented with Capri blue, faceted Swarovski crystals for a vibrant pop of color. This one-of a kind omega necklace is handcrafted exclusively for Uno Alla Volta, from the heart and hands of the artisan. No two are exactly alike. Each necklace measures approx. 2.5in. x 2in. pendant and 18in. silver-plated brass omega chain, with a pop clasp.
