This c. 1920's electric desk lamp with cased green shade is really nice!
A dedicated web sleuth and has informed me that the partial emblem still visible on the back of the shade is not that of Emeralite, but more likely Verdelite or Amronlite.
Fully-adjustable with beautiful brown patina. It also has a nice pineapple-type finial.
The shade has one small chip in the green part of the glass which doesn't go through the inner cased lining. It's a very small flake approx. 1/8" x 1/8" (see photo).
Professionally-rewired and ready to use.
DIMENSIONS: 17" high. Base measures 7" in diameter. Shade measures 10" long x 4.75" wide x 3.5" deep
