The Shades are Hexagonal, one of the border bars at the bottom fell off, I have though (see pic), it just needs epoxied back on. I searched high and low on all components of this lamp for any marks, also on the collars of the shades, zilch (the closest thing I can possible see as being a potential mark is shown in the photo of the top of the base, but I think it’s just part of the distressed finish in reality).
