I looked up outdoor tables in Travertine / Marble. Found a company in a different state to where I live that imports them from Overseas. They showed many designs from Italy but I picked an abstract in sand coloured Travertine with marble, abstract, angular pattern centre with modern design in black , white & choc. At 150cm round , 4cm thick , weighing 75kgs. Rock solid and looks beautiful with natural imperfections in the travertine ( a little rustic ). Can imagine it useful for many generations.

What colour is the shade? If white, then perhaps white side tables but change the handles/knobs to rose gold (if can find). It maybe a bit of a challenge but can you get a sample fabric and take it and the lamp to a furniture store?

They're hard to find - I searched for ages and finally fluked the pair that I got in a cheapo little furniture place that I almost walked right past (I only went in because I was sick of looking). You could always have them made - find a style you like then take it to a carpenter/cabinet maker if you can afford that - otherwise my suggestion is keep looking in those furniture shops that you wouldn't normally check out.

Looks great! I hope you don't mind my saying ... we have some lovely lamps and accessories for you're spruced up room :) although I can't see the rest of the room, the attached mirror comes to mind as a possible option for you.
