Black Basalto Basalt
Black basalto is the same with Grey Andesite an extrusive igneous and volcanic rock with aphanitic to porphyritic texture and it is not just made out of one stone but it is a mixture of gray rocks, white and light grays, hornblendes, black augites, feldspar and biotite. But it has white spots.
Due to mixture of several minerals, Andesite color composition is never the same, hence each product surface will always be unique, elegance and give off an impression of sophistication. The stone has 3 basic color variations; it can be grey, red and black andesite.
