Blue Antique Granite Blocks

Blue Antique® is slightly different to our other granite stones, with its unique warm brown colour, and blue and turquoise crystals. Blue Antique® can be cut in any direction, as crystals and colouring are strong and evenly spread, meaning that first choice materials can be sourced from second and third choice blocks.
