As found on internet” If your Murano glass earrings have "BRONZE" and "ITALY" stamped on the wire, it means your earrings were made by Italian artisans, likely crafted with a layer of bronze aventurine (a sparkling, copper-colored glass effect) or paired with a base-metal finding from an Italian manufacturer.” “Multi-Colors (Millefiori): Those tiny, colorful patterns inside the glass are made using special glass canes that look like cross-sections of flowers or stars. Artisans arrange these mosaic-like slices together while hot to form the heart shape.The Gold Shimmer: The gold you see inside the glass is genuine 24-karat gold leaf. During the blowing process, the artisan rolls the hot glass over thin sheets of real gold, causing it to break apart into beautiful, shimmering flecks trapped inside the clear glass layer.”
