Pictures with bases are to show LIT. I do have various bases. 18 inch diameter stained glass shade, approx 9 deep. Made extremely well using many pieces of glass, although a newer vintage shade the glass & crafting, especially in the inner solder lines, reminds me of the works of some of the more elaborate Gorham's / Amboy shades, lamps that were made in the Tiffany Era, early 19 hundreds.
Many small pieces of glass applied in this shade with exquisite dichroics emmiting fiery reds, mottled glass throughout among the quartz & oval shaped cathedral windows. Condition is excellent with minor stress if any as is normal with stained glass, however I do not see any cracks. I took a few with various light and in the natural to give you better look since everyone sees color little different. It is as nice as the pictures. A nice conversation piece, many compliments on the fiery look and geometrics.
Use a dimmer for desired effect, turn back for a soft nightlight when needed, Ambiance.
