Murano glass ring made by melting together sections of glass rods in a furnace, with each section depicting a small decorative motif. Once melted, the small plates are then tumbled in a rotating barrel using a secret process to smooth and polish the surface. Adjustable width. Each ring is marked with the “Vetro artistic Murano” brand that certifies its origin. Nickel-free, silver-plated copper. Sold with gift box.
