A core of goldstone under Effetre clear glass with blue bands at both ends. The silver/black webbing on the surface of this bead came from applying a Hades unique stringer that was approx 0.8mm wide and melting it down flat in a fairly hot, slightly oxygen rich flame.
I made this bead in summer 2011.
