Petrografic name (according EN 12407): Marble
Macroscopic description: A compact, aphanitic lithotype that is white verging on light grey in colour with frequent grey veins micrometric in thickness with a more or less perpendicular orientation. There are frequent dark grey subrounded patches and spots up to subcentimetric in size. Surface pores are scarce.

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 or the easy way.

Microscopic description according to EN 12407 e EN 12460
A crystalloblastic metamorphic lithotype composed of calcitic blasts of varying dimensions (from 60 to 600 µm) of a subeuhedral/euhedral shape with sutured or straight grain boundaries. The structure is anisotropic due to the preferential orientation of the foliation. The veins are composed of calcitic crystals that are particularly clouded by opaque minerals and blister inclusions, calcitic microblasts (20 ÷ 30 µm), idioblastic pyrite (< 20 µm), quartz and feldspars (< 350 µm) and acicular muscovite.
