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.
Name: Hellvik
Location: Egersund, Norway
Current production: 3-4,000 m³ per year
Potential production: 5,000 m³ per year
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.
