This 12mm square Murano Glass Bead features a core of Cobalt Blue transparent class decorated with splashes of 24kt Gold Foil and all encased in a layer of clear glass which gives the bead depth and sparkle. A 1mm hole runs through the bead. The exact placement of color and gold foil varies as they are entirely handmade lampwork beads. Use these for dainty earrings and as accents with our other focal Venetian Beads.
