Twisted onyx and bronze lamp

Elegant lamp base in onyx and bronze. The base is in the shape of a twisted column. Vintage model, with a height of 39cm on a square base of 8.8/8.8cm. Condition: Some marks on the onyx, a small chip at the bottom of the twisted tube at the joint of the bronze ring. The gilding on the bronze part is patinated and varies in shine, with signs of oxidation around the socket. Wiring with a pull switch at the socket. The details are visible in the photos. The overall piece remains in good condition and retains all its refinement.
