Natural stone is perhaps the most ancient material that humankind has used to build. Its use, since ages, has determined a close connection between history and culture that remains strong and unchanged to this day. Natural stone is a non-metamorphic calcareous rock, highly resistant to humidity and impact. The durability of natural stone is remarkably high and if installed and maintained accurately, it can be preserved for millennia. Its natural beauty, resistance and durability still make it to this day, one of the most requested and used materials by architects and interior designers, in its diverse chromatic variety, for cladding as well as the decoration of urban, public and residential spaces.
