Natural stone and marble that is first sliced into sheets of 8mm thickness then cut into irregular pieces that range between 2-6cm. These pieces are then tumbled with sand to soften and smooth the sharp cut edges for a beautifully soft natural finish. Please remember that natural stone is porous and must be sealed to reveal it's true colour and to prevent staining by grout or wear. We sell these tiles in 250g and 1000g units as each piece weighs between 30-70g. 250g= +/-11 pieces, 1000g=+/-44 pieces
