Piece of green/black marble 671 x 1101 x 19 mm (Fingringhoe CO5)

A slab of green, black and grey marble. Probably from a fireplace. 671 x 1101 x 19 mm. One broken corner. Polished on one side. A few ring markings and other "stains" (which could be polished away). Colour is darker than the photos show - couldn't adjust for the light reflections from the polished surface. Collection only (it's very heavy).
