This rare Murano glass sconce is made from a burnished brass structure and an "incamiciato" orange/white Murano glass shade. The irregularity of the geometric shape is due to the handmade creation of the piece. Very good condition: no chips or cracks. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, Up to 250V (Europe/UK Standard).The wiring of this item may be original and might need replacement, if not specified otherwise.
