Pyramid-shaped segments made of natural travertine that form a fluted profile. Designed by Tom Caldwell, this lamp is a labor-intensive piece because the shape is hand-formed. The square-cut-corner empire shade made of bone-colored linen echoes the tones in the travertine body of the contemporary lamp. Because it is made of natural travertine, the tones and the pits in the stone will vary from lamp to lamp.
