Nero Marquina marble (mármol Negro Marquina) is a high quality, black bituminous limestone extracted from the region of Markina, Basque Country in northern Spain. This variety of natural stone gets its black color from naturally-occurring bitumen.
It is one of the most important "marbles" from Spain. It has a fine and compact grain with a black background and white veins, which can be abundant.
