I googled it before i posted
Why do you think this is a floor lamp? If you look closer on pictures the one I have and the ones on google you will see the difference. It's not the floor lamp, pendant neither the wall sconce, as they have different attachment mechanisms.

ummmm...how about removing...
Ummmm...how about removing 'floor' from your google search, you will see all different types of RAAK lamps

I find the negative feeback...
I find the negative feeback somewhat unfair. I have the floorlamp myself and it is indeed quite different.
I know several other types but can't identify this one.
It seems intented to be fixed to the wall, no?

Yes, this does appear...
Yes, this does appear different than the floor lamp. This is why I suggested to do a broader search.

i did really searched for it
really long before I posted. I did not even know this is a RAAK at first. I just thought someone might have same one. The wall lamp might be the closest, still different.

Anyway what would you recommend I do for the base. Small marble piece, concrete, wood base? Any suggestions?

Is there any wear on the meta...
Is there any wear on the metal which may indicate how it was originally used? Did it fit in a base or perhaps a wall bracket?

My guess is that it was wall mounted,
and fit into a wall-bracket akin to the one in the photo below.
It's not unusual for wall brackets, screwed into walls, to get painted over(!), left behind, forgotten, lost.
One clue that suggests this may have been the case is that little collar on the vertical stem that might have prevented it from sliding down lower than desired.
Podboy's on the right track in asking if there's any telltale wear on the metal stem, from friction. Sometimes you gotta play Design Forensics Detective to solve these little mysteries.
(The sexy part's on the right >>> scroll to see)

Forgot to ask:
Is there an original PLUG on the end of that electrical cord?

some wear on the stem
There is some wear on the middle of the stem just before the stem widens. I appreciate the wall lamp picture. Bracket like that, yes, it may have been forgotten easily. If I remember the lady on the sale mention something about them being "in the wall". So that's probably it. I just need to get brackets like that. Thank you all.

I don't think it was fixed...
I don't think it was fixed to the wall as in the picture, your 'bubble' would drop out.
I think this would have been close to the wall, with the stem free, cable dropping down alongside the wall.
I made a schematic sketch how I think it could have looked.

Great schematic, bj--
but I don't see how the meat & potatoes is a great deal different from the wall bracket in the photo, when all is said & done: the stem needs to be inserted into some sort of "holster" attached to the wall.
Since the cord comes through the stem, however, the holster has to allow for this (you couldn't jam the plug through holes the circumference of the stem, needless to say).
Perhaps there should be two broken rings that hold the stem. The breaks in the rings big enough for the cord to fit through, but not big enough for the stem to fit through(?).

you're right whc, I wasn't...
you're right whc, I wasn't paying close attention.
couldn't you undo the internal fitting (within the lamp) of the cable and then put it back in place?

You mean, so that you could mount it using a bracket like the one you suggested?
Sure, you could dismantle the lamp from either end (including taking off the plug & putting it back on again) in order to fit it to such a bracket.
However, you'd then have to either put the lamp together again WHILE it was dangling from the wall --OR-- screw the mounted bracket to the wall WHILE the lamp was attached to bracket. Neither method would would be especially easy or pleasant; but where there's a will, there's a way.
All that ugliness could be avoided if there was a 3/8" break in whatever the stem fits into, allowing the cord to escape. (If I had more time, I'd make a diagram, but I gotta run--)
