Piasentina stone Technical data

The Piasentina stone appears with its unmistakable light grey colour, sometimes tending towards brown or reddish, barely veined with white and when the surface finishes vary, it responds with slight chromatic changes that, starting from the light grey of the sawn surface finishes, reaches dark grey shades after polishing, thus allowing different aesthetic combinations within the same material.

There are no other types of stone comparable to Piasentina stone, which lends itself to any kind of application, from building cladding (external and internal), to pavings, to design objects and works of art; thanks to its beauty, resistance, duration, workability and low water absorption coefficient.

The Piasentina stone was also awarded the “European Collective Mark”, which certifies its geological and mechanical properties, petrographic constitution, its origin and authenticity.
