Macroscopic description: A medium-fine-grained lithotype, pearly white verging on light grey in colour with dark grey veins of a vaguely sub parallel orientation and dark grey patches up to millimetric in size in places. The material is compact and there are no surface pores.

Block and slab characteristics
Average size of blocks: 3,00 x 1,70 x 1,70m. Slabs are preferably cut against the grain or perpendicular to the grain, i.e. the hard way and the easy way.

Microscopic description according to EN 12407 e EN 12460
An isotropic metamorphic lithotype, that is anisotropic where the veins occur. The material is composed of blasts that are subeuhedral and euhedral in the suborder with sutured/linear or rounded grain boundaries of a seriate size (from 50 to 400 μm). There are also millimetric nodules in places composed of larger crystals (500-900 μm) and veins composed of calcitic microblasts (approx. 40 µm) and rhombic dolomitic blasts clouded by opaque minerals, acicular muscovite, rare poikilitic quartz with inclusions and widespread pyrite microcrystals (< 30 μm).
