Millstone limestone tiles are a beautifully deep, blue-grey tumbled flagstone, with gentle flowering movement. This limestone tile works wonderfully in busy areas of the home, thanks to its tumbled finish that showcases natural stone markings, texture and worn edges. The Millstone tumbled limestone is also available in a 200x200x20mm exterior paving brick. This can be used as a perfect edging stone, alongside our paving, such as our Dijon Limestone Pavers.
