These authentic Murano Glass beads feature both 24kt gold foil and .925 sterling silver foil encased in two colors of Murano Glass. The shape is our new Vela Square which has rounded edges and is slightly thicker in the middle. The use of the gold and silver foils give are a great example of how we get varied colors by introducing metals into the beads. The colors on this bead are Blue and Aqua Murano Glass which appear brighter over the silver and take on the gold tones over the gold foil.
