cute! I am sure it's called a pine cone lamp because there are pine cones on the base and they didn't know what else to call it.
Is there any marking on it, anywhere? The wiring is new, replaced not too long ago, so that gives no clue. It's art Nouveau, so that puts it about the turn of the 20th century.
What is the metal? The base looks like bronze or brass....but the shade appears rusty? and the the motif on the shade doesn't match that on the base.....but I see no way it could be a marriage.
Do a google image search for things like "art nouveau pine cone lamp" or bronze pine themed lamp see if you can locate it's twin.

Nice lamp!!

Art Nouveau C1900, beautiful lamp. Looks like the original patina on the shade has been dusted away over the years where as it's still much more visible on the base. It's missing the beading which would have shaded the bulb. The amber roundels on the shade need cleaning up too. I have a very similar style lamp but with a poppy motif.

I love it! Can you show it with the light on?

Love the lamp! It so reminds me of the plant in Little Shop of Horrors! What a conversation piece. Thanks for sharing it.
