$80 - MCM Green Glass Table Lamp

I think the price might be a bit high...? But it's still pretty swanky - I love the green and brass look (well, "brass plated steel").

$220 - Green Stoneware Table Lamps

I'm admittedly pretty obsessed with this bright green. I've somehow managed to get it everywhere in my kitchen - salt and pepper grinders, kitchen timer, measuring spoons, spatulas, you name it. The best of course being these priceless salt and pepper shakers gifted by my Mother while I was still in college...

The seller notes that these do not come with a shade - which, with older lamps, is sometimes for the best - an updated shade can give new life like you wouldn't believe! When in doubt about any lamp, buy a new shade before giving up on it - you might suprise yourself. Lamps Plus has a great selection of contemporary shades.

Approximate Size:

Height to top of socket: 16.5"

Widest diameter 9.5"

Height of stoneware base: 12"

Base diameter: 4.5"

Height to top of harp: 23.5"

Weight: 7.2 lbs. each

$175 - 1960s Stiffel Lamp

I just know that this is perfect for someone. Its got color, class, and size. A little research (as the seller has done) shows a pair of these lamps ranging from $2-3,000. I love the red shade used on this pair on 1st Dibs. The Stiffel Lamp Company opened in Chicago in 1932 and specialized in a unique foil signature from pewter, brass and bronze. The price is right for a little bit of drama...

Height to top of socket: 32"
Height to top of harp: 38.5"
Height to top of shade: 41"
Ceramic base height: 16"
Ceramic base widest diameter: 7"
Brass Base: 7.5" diameter
Shade: 18" high x 17" bottom diameter x 15.5" top diameter
