Ultra opulent lamp and companion table

I just acquired this set at auction and I've fallen in love. It seems to be one of a kind because I can't find anything like it. It's 6 feet tall and gives off the softest glow of any lamp I've ever owned. There's 3-way light in the shade part and 3 combinations of "night-light" in the crystal section. It's made of heavily guilded cast iron, carved wood, crystals and what appears to be pressed tin. The table top is a golden-colored mother of pearl. It really doesn't go with my transitional style home, but I love it.

I have no idea what decade it's from, or even what country it might be from. My neighbor calls it my "Graceland" lamp. :-)
