Sicily pitch stone

Sicily Pitch Stone is a type of limestone which is characterized by different percentages of bitumen. This morphologic origin makes the pitchstone particularly unique for its peculiar chromatic shading. In fact, the pitchstone is also called "asphaltic stone" because it has a color that goes from gray to dark brown, while the parallel presence of fossils and grains gives it much more value by defining it in an unambiguous way. Moreover, the pitchstone hits the senses, in fact this stone transmits very particular feelings by touching it.
