What kind of "identification" do you want? it's an older lamp, likely the base is marble and the metal maybe gilt? ormolu? Does it hold a magnet? Appears to be milk glass and to have been rewired.

Thank you for the reply it definitely is stone the pictures don't show it great here is another photo in better light. We used a high powered light behind it to try and show the stone more. Only the base plate is magnetic and the rod that goes through the stone. the decorative pieces are not magnetic. Looking for era, style, possible maker/brand and estimated value. Thank you again.

Not alabaster...it's not translucent that I can see.
The stuff that holds a magnet is ferrous ( iron or steel) and the rest is likely brass covered in gilt. It appears classical in styling....could be anywhere from the 20's to maybe the 70's....given the chain pulls.
Worth? What someone will pay. Is there a shade?
It's not a style in demand that I know of...Maybe $25?

This was as close as I could find on ebay; presumably you've searched there? Perhaps this dealer could help you i.d. it.

This one popped up on pinterest, was listed on ebay for 149, but says it's out of stock. No way to know if it actually sold for that. Yours looks much finer than either of these examples. This dealer has many vintage lamps for sale. You might also contact them: https://www.ebay.com/usr/sunzza

I suggest you search sold listings...
