Tiffany 24" Clematis Cone in green

I made this lamp several years ago. It is a loose copy of the Tiffany Clematis, except that work is smaller (20") and has no repeats while mine is 24" with one repeat. The lamp and fixturing are copper plated with a rich brown patina. The background glass is Oceana and the flower glass is Uroboros. This shade was sold in November 2017 for $900.
