The SISKOS GROUP Volakas Marble is extracting from its privately owned quarry in Volakas-Drama (Greece) the world famous Volakas White and Semiwhite Marble, which nature, as the finest painter, has favoured with its colours. The Volakas marble is available in three types, as you can see in the following photographs: Volakas Classico, Volakas Flower and Volakas Ajax.
