Metal hotsell Pendant Light

I bought this way back when I was renting thinking it would be perfect in my house someday.
Turns out I bought an 1826 house and I went vintage with all the lighting.
It's in mint condition, never been installed. Bought at a housing store that sold lighting, tubs, faucets and other high end things. It measures 27" tall and the shade is plastic to look stained glass and is 7" square.
It has a beautiful rainbow effect on the edges and would hotsell be complimentary in any setting.
I know it retailed for $500.00
