Leon Nussbaum, our London silversmith, hand-sets Mexican fire opal into shimmering sterling silver to create these exquisite Mexican opal teardrop earrings. This jewelry sparkles with a mix of dazzling red, orange, and green hues produced by the diffraction of white light through a microstructure of silica spheres. Handcrafted exclusively for Uno Alla Volta, from the heart and hands of the artisan. Dimensions- approx. 1.25 inches long, posts.
