Authentic Murano Glass bead in a 18mm Round (approximately) with a 1mm hole through the center. It begins with the transparent acciaio (steel gray which appears more olivine over the white gold foil) which encases the white gold foil. A wide sash of Aventurina goes around the middle with a fenicio design adding to the style. These are fantastic and match all our solid color Gold Foil Beads.
