BLUE ANTIQUE® #7

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.

BLUE ANTIQUE® #7 Quarry

The development of our Blue Antique® quarry in Egersund continues and a large new area has been acquired, securing future supplies. The quarry has been widened and we are producing on several levels. Due to the characteristics of the deposit, we have a substantial production of large blocks in second and third choice.
