Dark grey marble, fine grain with thick light grey veins. Grey colour depends on microcrystalline pyrite.
Blocks usually have dimensions adaptable to diamond gangsaws ( 3,20×1,50×1,40 m), they have, when allowed from the quarry state,a side parallel to the vein direction to make possible cross cuts or vein cuts.
Slabs usually have 2 or 3 cm. thickness but for particular jobs they can have a minimum thickness of 1 cm.
The best result for this material when cut in slabs is polished or honed. The material is specified for interior and exterior jobs.
